2.0 Quick Start
This chapter is based on testing of E108-GN01.
1. First, the user needs to connect the GPS antenna, connect the computer with a USB cable, and then press the switch
button to turn on.
2. The user needs to short-circuit the RF_POWER two pins of the active antenna with jumpers.
3. User can open the serial port assistant to view the data sent by the serial port, or you can use our naviTrack to view.
When the baud rate is set to 9600 bps, the data will always be reported after closing the serial port. The common
output format is as follows:
GGA: time, location, number of satellites;
GSA: GPS receiver operation mode, satellite used for positioning, DOP value, positioning status;
GSV: visible GPS satellite information, elevation angle, azimuth angle, signal-to-noise ratio;

RMC: time, date, position, speed;
VTG: ground speed information;
For detailed meaning, please refer to the third section NMEA0183 protocol;
For ease of use, we recommend using the dedicated tool TaviTrack for debugging. For details, see the "naviTrack
User Manual".
1. Run naviTrack as administrator, run the above page;
2. Select the corresponding com port and click connect. After the connection is successful, you can see the reported
data in the NMEA window.
3. For the detailed meaning, please refer to the description in the third section NMEA0183 protocol;
4. After successful positioning, you can get the latitude and longitude information in the $ GPRMC field reported
by the serial port. For more detailed tool usage information, please refer to the manual in the toolkit.
5. Notice: Please refer to the corresponding user manual for the detailed software guide and software functions of
the E108-GN01 module.
