positioning and navigation module. It is small in size and low in power consumption. It can be used for

GNSS positioning such as car navigation, smart wear, and drone flight control. Application. Provides

hardware interface, supports UART communication and low power consumption mode. Support

BDS/GPS/GLONASS/GALILEO/QZSS/SBAS and other satellite positioning.

The module adopts the integrated design of radio frequency baseband antenna,

integrates DC/DC, LDO, radio frequency front end, low-power application

processor, RAM, Flash storage, RTC and power management, etc. It is powered

by button battery RTC and backup RAM. Reduce first positioning time. The

module supports serial port to connect with other peripherals, and the operation

is simple, and it will automatically start running after power on. Allow users to

get started very quickly.

1.3 Application scenario

Vehicle positioning and navigation equipment;

Wearable devices, such as GPS trackers, etc.;

UAV positioning, industrial computers, etc.;

Industry equipment that requires GNSS positioning or navigation；

Chapter 2 Quick start

This chapter is tested based on E108-GN02D:

1. Connect to a computer through a serial converter.

2. You can open the serial port assistant to view the data reported by the serial port, or use our

naviTrack to view.

Chengdu Ebyte Electronic Technology Co., Ltd. E108-GN02D User Manual

When the baud rate is set to 9600 bps, data will be reported all the time after opening the

serial port. The common output format is as follows:

GGA: time, location, number of satellites;

GSA: GPS receiver operating mode, satellites used for positioning, DOP value, positioning

status;

GSV: visible GPS satellite information, elevation angle, azimuth angle, signal to noise ratio;

RMC: time, date, location, speed;

VTG: ground speed information;

For detailed meaning, please refer to the third section NMEA0183 protocol;

For ease of use, we recommend using the exclusive tool TaviTrack for debugging. For

detailed usage, please refer to the "naviTrack User Manual".

Chengdu Ebyte Electronic Technology Co., Ltd. E108-GN02D User Manual

1. Run naviTrack. with administrator privileges, 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 detailed meaning, please refer to the description in the third section NMEA0183

protocol;

4. After the positioning is successful, 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 user manual in the toolkit。

Chapter 5 Hardware Design

It is recommended to use a DC stabilized power supply to power the module, the power supply

ripple should not exceed 30mV, and the module must be reliably grounded;

Please pay attention to the correct connection of the positive and negative poles of the power

supply. Reverse connection may cause permanent damage to the module;

Please check the power supply to ensure that it is within the recommended power supply voltage.

If it exceeds the maximum value, it will cause permanent damage to the module;

The serial ports TXD and RXD are LVTTL levels. If connected to a PC, RS232 level conversion

is required. User can use this serial port

Receive positioning information data and software upgrades.

This module is a temperature-sensitive device, and drastic changes in temperature will reduce its

performance. Try to stay away from high-temperature airflow and high-power during use.

Heating device

When designing the power supply circuit for the module, it is often recommended to reserve more

than 30% of the margin, and the whole machine is conducive to long-term stable operation;

The module should be as far away as possible from power supply, transformer, high frequency

wiring and other parts with large electromagnetic interference;

Assuming that there are devices with large electromagnetic interference around the module, it will

greatly affect the performance of the module. According to the intensity of the interference, it is

recommended to stay away from the module. If the situation permits, proper isolation and

shielding can be done；
