Summary Introduction A8 GNSS RTK system adopts modularized design, so as to enable users to change into different differential transmission modules according to various requirements. Those are traditional radio transmission, GPRS and 3G communication functions. Meanwhile the designed self-diagnosis function can autom atically check the working status of all hardware and software of the A8 receiver while working, and arouse the problem part by its intelligent voice messenger in case of some problem . Data collection controller can be connected with receiver mainframe via Bluetooth or cable; built-in high-capacity battery is suitable for long-time field work; static data can be stored in the built-in memory card of receiver and downloaded via USB port to your PC. Tips: 1. A8 GNSS RTK system has many modules. This manual does not represent standard configuration. Users need to notify their own requirements for the different configuration due to different appplications. 2. And before using, we suggest users firstly to check whether the package box is damaged, and then open careful and check whether inner items matched with the order list of their own. If there are some missing or damaging cases exist for products and accessories, please contact with the local 4
A8 GNSS RTK System Operation Manual distributor or Hi-Target Foreign Trade Dep. Immediately. 3. Last but not least, please carefully read manual before carrying, handling and using! Product Features 1. BD970 mother board of Pacific Crest, a Trimble Company, multi-satellite, multi-system kernel. 2. 1+X multi-module communication units. 3. PCC Radio module (optional) compatible with Trimble/Leica RTK. 4. Double battery capacity as 4400mAh, 12 hours for RTK operating. 5. The highest performance in waterproof, dustproof and anti-drop. 6. Adjustable to be single GNSS system or multi-GNSS system: GPS, GLONASS, GALILEO. Usage and Notes Although A8 receiver using chemical and impact resistance material, but necessary taking care and maintenance is still required for such a precise instrument. 5
Summary Warning: The receiver must be used and stored in the specified temperature. More details please refer to Chapter 7: Technical Parameters. To ensure the quality of continuous tracking satellites and signals, surveying work should be in open air, while there should no any obstacle in space above 15° altitude angle; in order to reduce all kinds of electrical interference to the GNSS satellite signals. Besides, there should not be strong electrical interference around within about 200m range, such as the television tower, microwave stations, high voltage transmission line. Also, in order to avoid or reduce the occurrence of multi-path effect, stations should be away from terrain or geographical objects, which will strong effect electrical signal, such as high-rise buildings, big pool, etc. Changes or modifications not expressly approved by the party responsible for compliance could void the user?ÿs authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: --Reorient or relocate the receiving antenna. --Increase the separation between the equipment and receiver. --Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help. The device must be operated to provide a separation distance of at least 20cm from User. 6

After connected with contro ller, using Hi-RTK software to set. Note: 1. The channel of rover m ust be the same as that of base, only in which case they can cooperate together. 2. Try to use the channel in a good environment with less interference. The below way is offered for users to find a good channel: - Firstly don’t set base, just set the rover in one channel - Check the data led (the middle led) of the rover. If the red led flashes, it hint s that there are some other transmitting data around i n this channel. You should change to another channel until you find a channel with no interference. - After you find a good channel, setting your base to this channel and start your work.

C H A P T E R 6 Static Collecting Chapter Introduction ■ Introduction ■ The procedure of A8 static survey ■ Download data with USB ■ Management software operat ion for Static Survey 52
A8 GNSS RTK System Operation Manual Instruction A8 receiver can be used as dual-frequency static surveying instrument. The collected static survey data is saved in the memory in the main frame. The static survey data have to be downloaded to PC with post-processing software to process. The procedure of A8 static survey 1. Locate the instrument on a point, centering and leveling it. 2. Measure the height of instr ument for three times, on condition that the difference of e ach measuring is less than 3mm and the final height of the instrument should be the average height. The height of instrument should be defined from the controlling point of base centre to upper edge of marker line. The antenna radius of A8 receiver is 0.087 meter; the height of phase center is 0.065 meter. Instrument height measure point Figure 6-1 Instrument height measure point 3. Record the point name, instru ment S/N, instrument height and observing initiated time. 4. Turn on the instrument and set it to static surveying mode. 53
Static Collecting The satellite led flashing means th e instrument is tracking the satellites. The satellites are locked once the satellite led turns into constant on. Status led flashes due to your collection interval. If setting the interval to 1 second the led will flash once a second. 5. Turn off the instrument after the static survey is finished and record the turn-off time. Download and post-process t he data Note: Don’t move or change the collecting setting while the instrument is collecting data. Download data with USB drive The data of A8 receiver can be downloaded with USB drive, use the Y type data cable, connect one side to USB port of PC and the other side to the 8-pin jack of main frame. After connecting, you will see a folder named GNSS in the PC, the static data are here, you can copy the according files directly.
