You can start measuring once the GPS positioning has been performed and thisinformation has been received. You can receive more detailed GPS navigation data (satellite orbital information) if youwait 15 minutes aer initial GPS signal acquisition, which improves measuring accuracy.However, note that GPS positioning is not 100% accurate or reliable at all times even with the more detailed GPS databecause of atmospheric conditions and the usage environment.NoteAGPS - Reducing the GPS Positioning TimeYou can reduce the GPS signal acquisition time by connecting the device with a smartphone and then retrieving GPSsatellite information from a network server.
