CHAPTER2Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 5Overview 2In this chapter:QFeaturesQUse and CareQCOCOM LimitsThis chapter introduces the Trimble® R7 GPS receiver. This receiver is designed for GPS surveying applications. The receiver features one-touch logging for ease of use, and five LEDs that enable you to monitor the survey in progress and the available battery capacity.The receiver tracks GPS satellites on both the L1 and L2 frequencies to provide precise position data for land survey applications. The receiver records GPS data on an internal CompactFlash card and makes all data available through serial or USB ports.You can use the Trimble R7 GPS receiver alone by logging data internally, or as part of the GPS Total Station® system, which logs GPS data from the receiver to a Trimble controller running the Trimble Survey Controller™ or Trimble Survey Pro™ software.

2 Overview6 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 2.1 FeaturesThe receiver provides the following features:•Trimble R-track technology, which enables the receiver to track the L2 Civil signal (L2C)•Centimeter-accuracy real-time positioning with RTK/OTF data, and up to 10 Hz position updates•Submeter-accuracy real-time positioning using pseudorange corrections•Adaptive dual-frequency RTK engine•WAAS/EGNOS capability (Wide Area Augmentation System/European Geo-Stationary Navigation System)•Automatic OTF (on-the-fly) initialization while moving•1PPS (One Pulse Per Second) output•Dual event-marker input•USB port for data transfer•Type I CompactFlash card for data storage•Internal charging of batteries (no external battery charger required)•Three RS-232 serial ports for:– NMEA output–RTCM SC-104 input and output– Trimble Format (CMR™) input and output•Two TNC ports for connecting to the GPS and radio antennas2.2 Use and CareThe Trimble R7 GPS receiver can withstand the rough treatment that typically occurs in the field. However, the receiver is a high-precision electronic instrument and should be treated with reasonable care.CWARNING – Operating or storing the receiver outside the specified temperature range can damage it. For more information, see Physical specifications, page 56.High-power signals from a nearby radio or radar transmitter can overwhelm the receiver circuits. This does not harm the instrument, but it can prevent the receiver electronics from functioning correctly. Avoid using the receiver within 400 meters of powerful radar, television, or other transmitters. Low-power transmitters such as those used in cellphones and two-way radios normally do not interfere with receiver operations.For more information, contact your local Trimble distributor.

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 7Overview 2Trimble R7 GPS Receiver Operation 2.3 COCOM LimitsThe U.S. Department of Commerce requires that all exportable GPS products contain performance limitations so that they cannot be used in a manner that could threaten the security of the United States. The following limitations are implemented on the Trimble R7 GPS receiver.Immediate access to satellite measurements and navigation results is disabled when the receiver’s velocity is computed to be greater than 1000 knots, or its altitude is computed to be above 18,000 meters. The receiver continuously resets until the COCOM situation is cleared.

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 25Setting up the Receiver 3Trimble R7 GPS Receiver Operation 30.2 AntennasThe Trimble R7 GPS receiver should normally be used with a Zephyr or Zephyr Geodetic antenna, which have been designed specifically for use with this receiver. Use Figure 3.14 as a guide for measuring the height of the Zephyr and Zephyr Geodetic antennas. The Zephyr antenna is designed to be measured to the top of the notch. The Zephyr Geodetic (shown) has been designed to be measured to the bottom of the notch. Figure 3.14 Measuring antenna heightOlder models of antennas, such as the Choke Ring or Micro-Centered™ L1/L2 antennas, need more power to operate than the Zephyr models. To configure the receiver to output more power on the antenna port, select the correct antenna type in GPS Configurator, or through the Trimble controller. For information on how to do this, contact your local Trimble Service Provider.30.3 CompactFlash cardsThe Trimble R7 GPS receiver logs data internally on a CompactFlash card. However, it only support the Type I CompactFlash card. Trimble recommends that you use an industrial-rated CompactFlash card, as commercial cards have a limited operating temperature range.Before logging data to a CompactFlash card, format the card to ensure the integrity of the file system. To format the card, insert it in the receiver and then hold down the power button for 30 seconds. Note – Make sure that you format your CompactFlash card in the receiver. This prevents data on the card from being corrupted if the card is removed while data is being logged. Formatting the card in your computer may cause data corruption, or loss of data.1.5201.5101.5151.505

A quick format reformats the card for use with the Trimble R7 GPS receiver and deletes all data on the card. A full format checks the card for errors or bad sectors, and is only necessary if the card is corrupted. To perform a full format, use the GPS Configurator software. For more information, see The GPS Configurator software, page 50.4.8 Batteries and powerCWARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery can cause an explosion or fire, and can result in personal injury and/or property damage. To prevent injury or damage: – Do not use or charge the battery if it appears to be damaged. Signs of damage include, but are not limited to, discoloration, warping, and leaking battery fluid.– Do not expose the battery to fire, high temperature, or direct sunlight. – Do not immerse the battery in water. – Do not use or store the battery inside a vehicle during hot weather. – Do not drop or puncture the battery. – Do not open the battery or short-circuit its contacts.

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 33General Operation 4Trimble R7 GPS Receiver Operation The Trimble R7 GPS receiver can be powered either by its two internal batteries or by an external power source connected to Port 2 or Port 3. The charge provided by the internal batteries depends on the type of survey and operating conditions. Typically, one battery provides about 3.5 hours of power during an RTK survey using the internal radio, and about 5 hours during a survey without the internal radio.The external power source is always used in preference to the internal batteries. When there is no external power source connected, or if the external power supply fails, the internal batteries are used. The internal batteries are drained in turn, and the receiver automatically switches to the full battery when the first battery is drained.If no external power is supplied and both internal batteries are drained, none of the data that you have logged is lost. When internal or external power is restored, the receiver restarts in the same state as when power was lost. For example, if the receiver was logging data, the data file is not corrupted, and when power is restored the receiver resumes logging with the same settings as before.The power supply that comes with the Trimble R7 GPS receiver charges the internal batteries while they are still in the receiver. To do this, connect the power supply to the power/serial data cable, connect the cable to Port 2 on the receiver and then connect the power supply to an AC power source, as shown in Figure 4.2. Figure 4.2 Charging the batteriesThe two internal batteries take approximately eight hours to charge. They are charged individually, so each battery takes approximately four hours to charge. The internal batteries start charging whenever an external power supply of greater than 15 V is detected.23Power/serial data cableTo AC power supply

However, the TSCe controller batteries and the Trimble R7 GPS receiver batteries can be charged at the same time from the same power supply. To charge both sets of batteries, use two standard power/serial data cables to connect the TSCe controller and the receiver to a power supply, as shown in Figure 4.3.Figure 4.3 Charging receiver and TSCe batteries23To AC Power/serial data cablespower supply

4 General Operation36 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 48.3 Power outputIf the receiver is being supplied with power from an external source, power is automatically output on Port 1. The output voltage is approximately 0.5 V less than the input voltage. Port 1 outputs a maximum voltage of 20 V, even if the input voltage is higher.You can use GPS Configurator or Trimble Survey Controller software to enable power output on Port 3. Port 3 can be enabled for power output regardless of whether power is supplied internally or externally.On Port 3, the output voltage is approximately 0.5 V less than the input voltage. For example, if power is being supplied from the internal Lithium-ion batteries, the maximum battery voltage is 8.4 V, so the maximum output voltage is 7.9 V.Note – When you start a survey using the Trimble Survey Controller software, and you are using an external radio, the software automatically enables power output on Port 3.48.4 FirmwareA receiver’s firmware is the program inside the receiver that makes the receiver run and controls the hardware. When you need to upgrade the firmware for your Trimble R7 GPS receiver, Trimble recommends that you use the WinFlash utility. For more information, see The WinFlash utility, page 50.CWARNING – Upgrading the firmware deletes all application files on the Trimble R7 GPS receiver.An alternative method of upgrading your firmware is to copy the .elf file directly to the CompactFlash card from your computer:1. Connect the CompactFlash card to your desktop computer.2. Using Windows Explorer, copy the .elf file from your computer to the CompactFlash card.3. Disconnect the CompactFlash card from your computer and insert it into the receiver.4. Turn the receiver off.5. Hold down [D] and press [P].The receiver starts up in Monitor mode, automatically detects the newer version of the firmware, and installs it. In Monitor mode, the red SV tracking LED is lit solidly and the yellow Logging/memory LED flashes slowly.The upgrade takes about two minutes. Once the upgrade procedure is complete, the receiver restarts automatically.

CHAPTER5Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 37Configuration 5In this chapter:QConfiguring the receiver in real TimeQConfiguring the receiver using application filesQApplication filesThe Trimble R7 GPS receiver has no controls for changing settings. To configure the receiver, use external software, such as GPS Configurator or Trimble Survey Controller.To configure the Trimble R7 GPS receiver, do one of the following:•Configure the receiver in real time•Apply the settings in an application fileThis chapter provides a brief overview of each of these methods, and describes the contents and use of application files.

5 Configuration38 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 5.1 Configuring the receiver in real TimeThe GPS Configurator and Trimble Survey Controller software support real-time configuration of the Trimble R7 GPS receiver.When you configure the receiver in real time, you use one of these software applications to specify which settings you want to change. When you apply the changes, the receiver settings change immediately.Any changes that you apply to the receiver are reflected in the current application file, which is always present in the receiver. The current application file always records the most recent configuration, so if you apply further changes (either in real time or using an application file) the current file is updated and there is no record of the changes that you applied originally.For more information on configuring the receiver in real time, see Chapter 7, Software Utilities.5.2 Configuring the receiver using application filesAn application file contains information for configuring a receiver. To configure a receiver using an application file, you need to create the application file, transfer it to the receiver, and then apply the file settings. The GPS Configurator software does this for you automatically when you work with configuration files.For more information on applying application files, see Chapter 7, Software Utilities.5.3 Application filesAn application file is organized into records. Each record stores configuration information for a particular area of receiver operation. Application files can include the following records:•File Storage•General Controls•Serial Port Baud/Format•Reference Position•Logging Rate•SV Enable/Disable•Output Message•Antenna•Device Control•Static/Kinematic•Input Message

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 39Configuration 5Trimble R7 GPS Receiver Operation •Timed ActivationAn application file does not have to contain all of these records. When you apply an application file, any option that is not included in the records in the file remains at its current setting. For example, if you apply an application file that only specifies the elevation mask to use, all other settings remain as they were before the application file was applied.You can store up to twenty different application files in battery-backed memory on the receiver. You can apply an application file’s settings at the time it is transferred to the receiver, or at any time afterwards.53.1 Special application filesThe Trimble R7 GPS receiver has three special application files, which control important aspects of the receiver’s configuration.Default application fileThe default application file (Default.cfg) contains the original receiver configuration, and cannot be changed. This file configures the receiver after it is reset. To reset the receiver, hold down [P] for at least 15 seconds, or use the reset option in the GPS Configurator software.For more information, see Default settings, page 60.Although you cannot change or delete the default application file, you can use a power up application file to override any or all of the default settings.Current application fileThe current application file (Current.cfg) reflects the current receiver configuration. Whenever you change the receiver’s configuration, either in real time or by applying an application file, the current file changes to match the new configuration.You cannot delete the current file or change it directly, but every change to the receiver’s current configuration is applied to the current file as well.When you turn off the receiver then turn it on again, all the settings from the current application file are applied, so you do not lose any changes that you have made. The only exceptions are the following logging parameters:•Logging rate•Position rate•Elevation maskThese parameters are always reset to the factory default values whenever the receiver is switched off.

5 Configuration40 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation Power up application filethe power up application file (Power_up.cfg) is optional. if a power up file is present, its settings are applied whenever the receiver is turned on.In this file, you can specify that the receiver is reset to defaults before the power up settings are applied. This ensures that restarting the receiver always results in the same configuration. This method is useful for defining “default” settings for the receiver that differ from those in the default file, which cannot be changed.Alternatively, you can specify that the power up settings are applied immediately after the current application file’s settings have been applied. Restarting the receiver results in a configuration that uses your default settings for the options you define in the power up file, but the current settings for all other options.By default, there is no power_up application file on the receiver. To use a power up application file, you must create and save a power_up application file in the GPS Configurator software. If you save this file to disk, the file is called power_up.cfg. The extension .cfg is used by convention to identify application files on the office computer. when you transfer this file to the receiver, the file is saved on the receiver as power_up, and becomes the new power up file.The power up file is the only special application file that you can overwrite or delete from the receiver.53.2 Timed application filesA timed application file contains a Timed Activation record which specifies when this file is to be applied. The main use of a timed application file is to automatically start or stop logging at a predefined time.The Timed Activation record specifies:•the UTC date and time when the application file is to be applied for the first time•the interval at which the file is to be reappliedIf you do not specify a repeat interval, the settings are applied only once, at the specified time. If the file specifies a repeat interval, the file’s settings are reapplied at the specified interval until the file is deactivated.Note – If the receiver is logging continuously, the current logging takes precedence over any timed application file stored in the receiver.Defining timed application filesTo send timed application files to a Trimble R7 GPS receiver, set up scheduled survey sessions in the GPS Configurator software. You can define multiple sessions, each specifying:•basic logging parameters (data logging rate, position logging rate, and elevation mask)

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 41Configuration 5Trimble R7 GPS Receiver Operation •a starting time•a durationWhen you apply the current settings in the GPS Configurator software, each defined survey session is sent to the Trimble R7 GPS receiver as a pair of timed application files: the first includes the logging settings and start time, and the second contains settings that stop logging at the end time (which is calculated automatically from the duration you specify).For more information on scheduled survey sessions, refer to the GPS Configurator Help.The receiver can store up to 20 application files, so you can define a maximum of 10 scheduled survey sessions (10 pairs of start/stop timed application files).Sleep modeWhenever you press [P] to turn off the Trimble R7 GPS receiver, the receiver checks for a timed application file that is due to be activated in the future. If one exists, the receiver goes into Sleep mode instead of turning off.In Sleep mode, the yellow Logging/Memory LED flashes every three seconds. The receiver wakes up five minutes before the scheduled activation time, so that it is ready to begin logging at the scheduled time.53.3 Applying application filesAn application file’s settings do not affect the receiver’s configuration until you apply the application file. You can do this at the same time that you save the file. Alternatively, save the file on the computer or in the receiver, then open it later and apply its settings.Note – If the application file is a timed file, its settings do not take effect as soon as you apply the file, but at the time that the file specifies for its activation.53.4 Storing application filesYou can store application files that you create in the GPS Configurator software on the receiver and on the computer. For example, each file can represent a different user sharing the same receiver, or a particular mode of operation or survey style. Saving application files on your computer as well as in your receiver is optional, but it is useful because:•it gives you a permanent copy of the settings you have sent to a receiver, for audit or your own reference.•you can use the same file to configure multiple receivers identically.•you can use an existing application file as a template to create other application files with similar settings.

5 Configuration42 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 53.5 Naming application filesThe application filename in the office computer and in the receiver is always the same. This makes it easier to recognize and keep track of your application files. When you change the name of the application file in the receiver, this changes the application filename on your computer. When you transfer an application file from the receiver and save it to the computer, the system renames the file to match the internal receiver file. However, if you use Windows Explorer, for example, to change the .cfg filename on the computer, this does not change the internal receiver filename. This means that the GPS receiver does not recognize the change to the filename on the computer.

These files cannot be processed until you transfer them to your office computer.Note – The receiver supports a maximum of 512 files on the CompactFlash cards.When you return to the office with a completed survey, transfer the field data to a computer that has the Trimble Geomatics Office™ software installed. You can then process the survey data in the Trimble Geomatics Office software to produce baselines and coordinates.

6 Transferring Data44 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 6.1 Connecting to the office computerThe Trimble R7 GPS receiver has three serial (COM) ports and one USB port to connect to the office computer. A USB connection is up to ten times faster than normal serial communications.Use the standard power/serial data cable to connect the receiver to the computer, as shown in Figure 6.1.Figure 6.1 Connecting the Trimble R7 GPS receiver to a computer for serial data transfer Power/serial dataPort 2Serial (COM) port cable

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 45Transferring Data 6Trimble R7 GPS Receiver Operation Use the USB cable to connect the receiver to the computer, as shown in Figure 6.2.Figure 6.2 Connecting the Trimble R7 GPS receiver to a computer for USB data transfer Note – When the receiver is connected to a USB port on a computer, it is treated as a peripheral device of the computer. If the receiver is unplugged or turned off, a warning message appears on the computer.6.2 Transferring dataTransfer the data files to the computer using the Trimble Data Transfer utility. You can run this utility as a standalone program or from within the Trimble Geomatics Office software. For more information, refer to the Data Transfer Help.Note – When you connect to a receiver in the Data Transfer utility, you must use a GPS Receiver (R/5000 Series) device definition. If you use a GPS Receiver (4000 Series) device definition, the Data Transfer utility cannot establish communication with the receiver.When transfer is complete, the Data Transfer utility automatically converts the file to the DAT format. If you are using Data Transfer from within the Trimble Geomatics Office software, the Check-in dialog appears. For more information, refer to the Trimble Geomatics Office User Guide.Note – A file in DAT format is approximately six times the size of the corresponding file in the Trimble R7 GPS receiver internal format. Before transferring files, make sure that there is enough space on your computer.USB cableUSB portUSB port

6 Transferring Data46 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 6.3 Transferring files directly from a CompactFlash cardIn a Trimble R7 GPS receiver, all data is stored on an internal CompactFlash card. There are two ways to transfer files between the receiver and the office computer:•Connect the receiver to the office computer and use the Data Transfer utility to transfer files.•Remove the CompactFlash card from the receiver and connect it directly to your office computer, where it functions like a normal disk drive. Use Windows Explorer to transfer files.When you use the Data Transfer utility to transfer data files from the CompactFlash card while it is still inserted in the receiver, the Data Transfer utility converts the raw receiver data (.T01) files you select into the Trimble DAT file format.However, if you connect the CompactFlash card to your computer and then copy or move files to your computer, it treats the card like any other disk drive, and transfers the files without converting them. You need to convert these raw receiver files to DAT format files before you can use them on your office computer.You can convert receiver data files using a Windows Explorer extension, which is installed on your computer when you install the Data Transfer utility. Note – Although this extension is only available if you have the Data Transfer utility installed, you do not have to run the Data Transfer utility to use it.To convert a .T01 file on your office computer into the DAT format:1. On your office computer, open Windows Explorer and navigate to the location of the .T01 file. 2. Right-click the file, and select Convert to DAT format from the shortcut menu:

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 47Transferring Data 6Trimble R7 GPS Receiver Operation The DAT File Conversion dialog appears while the file is converted. When the dialog disappears, the file conversion is complete.A new file with the same filename but a .dat extension appears in the same folder as the .T01 file.6.1 Deleting files in the receiverYou can delete files stored in the receiver at any time. Do one of the following:•Use the Data Transfer utility in the Trimble Geomatics Office software.•Use the TSCe controller.•Turn on the receiver and then hold down [P] for 30 seconds. When you use this method, all data is deleted, and the CompactFlash card is reformatted.•Use the GPS Configurator software.6.2 Supported file typesTable 6.1 shows the file types that you can transfer to or from a Trimble R7 GPS receiver, and the software or utility that you must use to transfer each file type.Note – The Trimble R7 GPS receiver supports a maximum of 512 files on the CompactFlash card.

The default application file, Default.cfg, is stored permanently in the receiver, and contains the factory default settings for the Trimble R7 GPS receiver. Whenever the receiver is reset to its factory defaults, the current settings (stored in the current application file, current.cfg) are reset to the values in the default application file.You cannot modify the default application file. however, if there is a power up application file (Power_up.cfg) in the receiver, the settings in this file can be applied immediately after the default application file, overriding the factory defaults.For more information, see Application files, page 38.

The receiver does not reset itself to defaults or apply any power up settings. If the receiver was logging when power was lost unexpectedly, it resumes logging when power is restored.However, when you turn off the receiver using [P], the receiver behaves as if you pressed [D] to stop logging before you pressed [P]. In this case, when power is restored normally, logging does not begin until you start it manually.93.4 Disabling loggingTo disable logging, you can set the receiver’s data logging and position logging rates to Off.

Sending an application file to the receiver does not necessarily apply the file’s settings; you can apply a file’s settings at any time after sending it to the receiver. You can also define timed application files. A timed application file contains receiver settings, but also includes a date and time when it is automatically activated.If there is a timed application file on the Trimble R7 GPS receiver, the receiver automatically applies the file’s settings and begins logging (if logging settings are included in the file) at the specified time. If the receiver is in Sleep mode, it wakes up five minutes before the start time of the timed application file, and then begins logging, if required, at the specified start time.When you send an application file to the receiver and …then the receiver settings are changed …you apply the file’s settings immediately as soon as you send the file to the receiveryou apply the file later as soon as you apply the fileit is a timed application file at the specified activation time

CHAPTER11Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 71Event Marker Input and 1PPS Output11In this chapter:QEvent marker inputQ1PPS outputThe Trimble R7 GPS receiver can accept event marker input on Port 1 and port 2, and can generate 1PPS output on Port 2.

11 Event Marker Input and 1PPS Output72 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R7 GPS Receiver Operation 11.1Event marker inputUse event marker input to log a precise GPS time tag whenever an externally generated pulse is received, such as one generated at the time of the shutter closing from a photogrammetric camera.The event is triggered when the source pulse voltage transitions between 1.0 V DC and 2.0 V DC in less than 100 nsec. Trimble recommends that you use TTL level inputs. You can configure the receiver to recognize either a positive (rising) or negative ( falling) voltage as the leading edge of a pulse. The accuracy of the associated time tag recorded for an event is determined by the GPS accuracy (typically less than 1 μsec.).The Trimble R7 GPS receiver records each event in the current data file. This record includes the port on which the event was received.111.1 Enabling and configuring event marker inputTo enable or configure the event marker input function, you need the GPS Configurator software.In real timeYou can use the GPS Configurator software to configure a Trimble GPS receiver connected to your office computer. For more information, see The GPS Configurator software, page 50, or refer to the GPS Configurator Help.To enable event marker input:1. Connect the computer to the Trimble R7 GPS receiver.2. Press [P] to turn on the receiver.3. To start the GPS Configurator software, click and then select Programs /Trimble /GPS Configurator /GPS Configurator. The GPS Configurator dialog appears and the software automatically connects to the Trimble R7 GPS receiver.4. In the General tab, select the Event marker check box.5. Select the appropriate option, Positive slope or Negative slope, depending on the type of pulse the external device uses.6. Click Apply.The GPS Configurator software sends the new configuration information to the receiver, and the receiver starts to accept event marker input.7. Click OK to exit the GPS Configurator software. The software disconnects from the receiver.

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 73Event Marker Input and 1PPS Output 11Trimble R7 GPS Receiver Operation 11.11PPS outputThe Trimble R7 GPS receiver can output a one pulse per second (1PPS) time strobe with an associated ASCII time tag output. The pulse is output through port 2 of the receiver using the event marker/1PPS cable. 111.1 1PPS pulse definitionThe leading edge of the pulse coincides with the beginning of each UTC second, as shown in Figure 11.1. The pulse is driven by an RS-422 driver between nominal levels of 0 V and 4 V. The leading edge is positive, rising from 0 V to 4 V.Figure 11.1 Time tag relation to 1PPS wave formThe pulse is approximately 8 μsec wide, with rise and fall times of about 100 nsec. Resolution is approximately 40 nsec, but several external factors limit accuracy to approximately ±1 μsec:•Position errors, especially with user-entered reference. Each meter of error can result in 3 nsec of error in the 1PPS pulse.•Antenna cable length. Each meter of cable adds a delay of about 2 nsec to satellite signals, and a corresponding delay in the 1PPS pulse.111.2 ASCII time tag definitionEach time tag is output about 0.5 second before the corresponding pulse, as shown in Figure 11.1. Time tags are in ASCII format on a user-selected serial port. The format of a time tag is:UTC yy.mm.dd hh:mm:ss abWhere:•UTC is fixed text.•yy.mm.dd is the year, month, and date.•hh:mm:ss is the hour (on a 24-hour clock), minute, and second.

The receiver clock is less accurate than time readings extracted from satellite signals.111.3 Enabling and configuring 1PPS output in real timeTo enable or configure the 1PPS output function, you need the GPS Configurator software. You can use the GPS Configurator software to configure a Trimble GPS receiver connected to your office computer.

14 General Operation92 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R6 GPS and R8 GNSS Receiver Operation Note – If you use the Data Transfer utility to download the internally-logged files, you lose any collected GLONASS data. Consider this if you plan to use the Trimble Geomatics Office software to process the *.dat files because that software does not process GLONASS data.If you have the Trimble Business Center software, the *.T01 file that is stored on the receiver can be directly downloaded. The *.T01 files will contain any collected GLONASS data because the Trimble Business Center software can process GLONASS data, if you have purchased that option.CWARNING – The receiver allows for a maximum of 200 files on the internal memory. The filenames must be in 8.3 format, otherwise, files copied to the internal memory may cause data corruption or loss of data when logging.Data is logged using the current logging settings configured in the receiver. Data files logged internally are named automatically. To begin internal logging, you must use a Trimble controller, or the GPS Configurator software. The receiver does not have an internal clock, so you can only conduct timed survey sessions if the receiver has a continuous power supply.When the internal memory is full, the receiver stops logging data, and the Logging/Memory LED turns off. Existing data files are not overwritten. You can use the Auto-delete option to override this action and automatically delete the oldest files when the receiver memory is full. However, you should use this option with caution because it can lead to data loss.Approximate storage requirements for different logging rates are shown below. The values shown are for a one-hour logging session with six satellites visible. 145.2 Logging to a Trimble controllerWhen the receiver is connected to a Trimble controller, you can log GPS data from the receiver to the controller, or to a PC card inserted in the controller. When you use a Trimble controller, you do not use the receiver’s controls. Instead, you use the controller functions to set logging options, specify filenames, and control when logging occurs.Data is stored in job files, which can be transferred to your office computer using the Trimble Data Transfer utility.For more information on logging data from a receiver using a Trimble controller, refer to the user guide for your particular controller.Logging rate Memory required10 Hz 2,588 KB1 Hz 335 KB5 seconds 87 KB15 seconds 37 KB

A damaged battery can cause an explosion or fire, and can result in personal injury and/or property damage. To prevent injury or damage: – Do not use or charge the battery if it appears to be damaged. Signs of damage include, but are not limited to, discoloration, warping, and leaking battery fluid.– Do not expose the battery to fire, high temperature, or direct sunlight. – Do not immerse the battery in water. – Do not use or store the battery inside a vehicle during hot weather. – Do not drop or puncture the battery. – Do not open the battery or short-circuit its contacts.The receiver can be powered by its internal battery or by an external power source connected to Port 1. Typically, one internal 2.4 ampere-hour battery provides approximately 5.3 hours of operation during an RTK survey using the internal radio in rover mode and approximately 3.5 hours of operation as an RTK base (this varies according to temperature and wireless data rate).If an external power source is connected to Port 1, it is used in preference to the internal battery. When there is no external power source connected, or if the external power supply fails, the internal battery is used. CWARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or property damage.To prevent injury or damage:– If the battery leaks, avoid contact with the battery fluid. – If battery fluid gets into your eyes, immediately rinse your eyes with clean water and seek medical attention. Do not rub your eyes! – If battery fluid gets onto your skin or clothing, immediately use clean water to wash off the battery fluid.The receiver is supplied with two rechargeable Lithium-ion batteries, and a dual battery charger. The two batteries charge sequentially and take approximately four hours each to fully charge.147.1 Battery charging and storageAll battery types discharge over time when they are not being used. Batteries also discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long periods of time, make sure it is fully charged before storing and re-charged at least every three months.

14 General Operation94 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R6 GPS and R8 GNSS Receiver Operation CWARNING – Charge and use the rechargeable Lithium-ion battery only in strict accordance with the instructions. Charging or using the battery in unauthorized equipment can cause an explosion or fire, and can result in personal injury and/or equipment damage. To prevent injury or damage: – Do not charge or use the battery if it appears to be damaged or leaking.– Charge the Lithium-ion battery only in a Trimble product that is specified to charge it. Be sure to follow all instructions that are provided with the battery charger. – Discontinue charging a battery that gives off extreme heat or a burning odor.– Use the battery only in Trimble equipment that is specified to use it. – Use the battery only for its intended use and according to the instructions in the product documentation.Charging the Lithium-ion batteryThe rechargeable Lithium-ion battery is supplied partially charged. Charge the battery completely before using it for the first time. If the battery has been stored for longer than six months, charge it before use.To protect the battery from deep discharge (5 V or less), the receiver is designed to switch batteries or cease drawing power when the battery pack discharges to 5.9 V.A battery that has reached the deep discharge level cannot be recharged and must be replaced. The following recommendations provide optimal performance and extend the life of your batteries:•Fully charge all new batteries prior to use.•Do not allow the batteries to discharge below 5 V.•Keep all batteries on continuous charge when not in use. Batteries may be kept on charge indefinitely without damage to the receiver or batteries.•Do not store batteries in the receiver or external charger unless power is applied. •If you must store the batteries, fully charge them before storing and then recharge them at least every three months.Disposing of the rechargeable Lithium-ion batteryDischarge the Lithium-ion battery before disposing of it. When disposing of the battery, be sure to do so in an environmentally sensitive manner. Adhere to any local and national regulations concerning battery disposal or recycling.147.2 Power outputThe receiver does not supply power from either of its two ports.

CHAPTER15Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 97Configuration 15In this chapter:QConfiguring the receiver in real timeQConfiguring the receiver using application filesQApplication filesThe Trimble R6 GPS and R8 GNSS receivers have no controls to change settings. To configure the receiver, use external software such as GPS Configurator, WinFlash, or Trimble Survey Controller.There are two ways to configure the receiver. You can:•configure the receiver in real time•apply the settings in an application fileThis chapter provides a brief overview of each of these methods and describes the contents and use of application files.

15 Configuration98 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R6 GPS and R8 GNSS Receiver Operation 15.1Configuring the receiver in real timeGPS Configurator and Trimble Survey Controller software support real-time configuration of the receiver.When you configure the receiver in real time, you use one of these software applications to specify which settings you want to change. When you apply the changes, the receiver settings change immediately.Any changes that you apply to the receiver are reflected in the current application file, which is always present in the receiver. The current application file always records the most recent configuration, so if you apply further changes (either in real time or using an application file) the current file is updated and there is no record of the changes that you applied originally.For more information on configuring the receiver in real time, see Chapter 16, Software Utilities.15.2Configuring the receiver using application filesAn application file contains information for configuring a receiver. To configure a receiver using an application file, you need to create the application file, transfer it to the receiver and then apply the file’s settings. The GPS Configurator software does this automatically when you work with configuration files.For more information on applying application files, see Chapter 16, Software Utilities.15.3Application filesAn application file is organized into records. Each record stores configuration information for a particular area of receiver operation. Application files can include the following records:•File Storage•General Controls•Serial Port Baud/Format•Reference Position•Logging Rate•SV Enable/Disable•Output Message•Antenna•Device Control•Static/Kinematic•Input Message

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 99Configuration 15Trimble R6 GPS and R8 GNSS Receiver Operation An application file does not have to contain all of these records. When you apply an application file, any option that is not included in the records in the file remains at its current setting. For example, if you apply an application file that only specifies the elevation mask to use, all other settings remain as they were before the application file was applied.You can store up to twenty different application files in the receiver. You can apply an application file’s settings at the time it is transferred to the receiver, or at any time afterwards.153.1 Special application filesThe receiver has three special application files, which control important aspects of the receiver’s configuration.Default application fileThe default application file (Default.cfg) contains the original receiver configuration, and cannot be changed. This file configures the receiver after it is reset. You can reset the receiver by holding down [P] for at least 15 seconds, or by using the reset option in the GPS Configurator software.For more information, see Default settings, page 116.Although you cannot change or delete the default application file, you can use a power up application file to override any or all of the default settings.Current application fileThe current application file (Current.cfg) reflects the current receiver configuration. Whenever you change the receiver’s configuration, either in real time or by applying an application file, the current file changes to match the new configuration.You cannot delete the current file or change it directly, but every change to the receiver’s current configuration is applied to the current file as well.When you switch off the receiver then turn it on again, all the settings from the current application file are applied, so you do not lose any changes that you have made. The only exceptions are the following logging parameters:•Logging rate•Position rate•Elevation maskThese parameters are always reset to the factory default values whenever the receiver is switched off.

15 Configuration100 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R6 GPS and R8 GNSS Receiver Operation Power up application fileThe power up application file (Power_up.cfg) is used to set the receiver to a specific configuration any time the unit is powered up. In this file, you can specify that the receiver is reset to defaults before the power up settings are applied. This ensures that restarting the receiver always resets it to factory defaults prior to applying the power up application file.Alternatively, you can specify that the power up settings are applied immediately after the current application file’s settings have been applied. Restarting the receiver results in a configuration that uses your default settings for the options you define in the power up file, but the current settings for all other options.By default, there is no power_up application file on the receiver. To use a power up application file, you must create and save a power_up application file in the GPS Configurator software. If you save this file to disk, the file is called power_up.cfg. The extension .cfg is used, by convention, to identify application files on the office computer. When you transfer this file to the receiver, the file is saved on the receiver as power_up, and becomes the new power up file.The power up file is the only special application file that you can overwrite or delete from the receiver.153.2 Applying application filesAn application file’s settings do not affect the receiver’s configuration until you apply the application file. You can do this at the same time that you save the file. Alternatively, you can save the file on the computer or in the receiver, then open it later and apply its settings.153.3 Storing application filesYou can store application files that you create in the GPS Configurator software on the receiver and on the computer. For example, each file can represent a different user sharing the same receiver, or a particular mode of operation or survey style. Saving application files on your computer as well as in your receiver is optional, but it is useful because:•it gives you a permanent copy of the settings you have sent to a receiver, for audit or your own reference.•you can use the same file to configure multiple receivers identically.•you can use an existing application file as a template to create other application files with similar settings.

Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 101Configuration 15Trimble R6 GPS and R8 GNSS Receiver Operation 153.4 Naming application filesThe application filename in the office computer and in the receiver are always the same. This makes it easier to recognize and keep track of your application files. When you change the name of the application file in the receiver, this changes the application filename on your computer. When you transfer an application file from the receiver and save it to the computer, the system renames the file to match the internal receiver file. However, if you use Windows Explorer, for example, to change the .cfg filename on the computer, this does not change the internal receiver filename. This means that the GPS receiver does not recognize the change to the filename on the computer.

For a copy of the NMEA-0183 Standard, go to the National Marine Electronics Association website at www.nmea.org.

A NMEA-0183 Output126 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User GuideTrimble R6 and R7 GPS/R8 GNSS Receiver Operation A.1 NMEA-0183 OutputsWhen NMEA-0183 output is enabled, a subset of NMEA-0183 messages can be output to external instruments and equipment connected to the Trimble receiver serial ports. These NMEA-0183 messages let external devices use selected data collected or computed by the receiver.All messages conform to the NMEA-0183 version 3.01 format. All begin with $ and end with a carriage return and a line feed. Data fields follow comma (,) delimiters and are variable in length. Null fields still follow comma (,) delimiters but contain no information.An asterisk (*) delimiter and checksum value follow the last field of data contained in an NMEA-0183 message. The checksum is the 8-bit exclusive OR of all characters in the message, including the commas between fields, but not including the $ and asterisk delimiters. The hexadecimal result is converted to two ASCII characters (0–9, A–F). The most significant character appears first.The following table summarizes the set of NMEA messages supported by the receiver, and shows the page where detailed information about each message can be found. To enable or disable the output of individual NMEA messages, do one of the following:•Create an application file in the GPS Configurator software that contains NMEA output settings and then send the file to the receiver.•Add NMEA outputs in the Serial outputs tab of the GPS Configurator software and then apply the settings.Message Function PageAVR Time, yaw, tilt, range, mode, PDOP, and number of SVs for Moving Baseline RTK128GGA Time, position, and fix related data 128GSA GNSS DOP and active satellites 129GST Position error statistics 130GSV Number of SVs in view, PRN, elevation, azimuth, and SNR 130HDT Heading from True North 131PTNL,GGK Time, position, position type and DOP values 131PTNL,GGK_SYNC Time, synchronized position, position type and DOP values 132PTNL,PJK Local coordinate position output 133PTNL,PJT Projection type 133PTNL,VGK Time, locator vector, type and DOP values 134PTNL,VHD Heading Information 134RMC Position, Velocity, and Time 135ROT Rate of turn 135VTG Actual track made good and speed over ground 136ZDA UTC day, month, and year, and local time zone offset 136
