Product Description

1.1. Key Features


1.2 Power Supply

Regulated power for the RB-1513G-MTGN is required. The VCC Pin Need a stable DC voltage supply. Power supply ripple must be less than 30mV. The input voltage Vcc should be 2.8V~4.3V, Recommended power supply voltage is 3.3V. maximum current is 40mA. Suitable decoupling must be provided by external decoupling circuitry.


1.3 UART Ports

   The module supports two full duplex serial channels UART. All serial connections are at 3V CMOS logic levels, if need different voltage levels, use appropriate level shifters. The baud rate of both serial ports are fully programmable, the data format is however fixed: X, N, 8, 1, i.e. X baud rate, no parity, eight data bits and one stop bit, no other data formats are supported, LSB is sent first. The modules default baud rate is set up 9600bps, however, the user can change the default baud rate to any value from 4800 bps to 115kbps. UART port can be used for firmware upgrade, NMEA output and PMTK proprietary commands input.



2 Application

   The module is equipped with a 7-pin pad that connects to your application platform. The RB-1513G-MTGN module It consists of a MediaTek MT3333 single chip GNSS IC which includes the RF part and Baseband part, a patch antenna, a LNA, a SAW filter, a TCXO, a crystal oscillator.

3 NMEA 0183 Protocol

   The NMEA protocol is an ASCII-based protocol, Records start with a $ and with carriage return/line feed. GPS&GLONASS specific messages all start with $GPxxx/$GLxxx where $GNxxx is a three-letter identifier of the message data that follows. NMEA messages have a check sum, which allows detection of corrupted data transfers.


3.1 Location mode configuration instructions

   Single system or dual system positioning mode can be selected through the configuration instructions,  configuration instructions such as Table 1.

Product Feature

RB-1513G-MTGN is a complete GPS & GLONASS engine module that features super sensitivity, ultralow power and small form factor. The GPS &GLONASS signal is applied to the antenna input of module, and a complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol. Its–165dBm tracking sensitivity extends positioning coverage into place like urban Canyons and dense foliage environment where the GPS & GLONASS was not possible before. The small form factor and low power consumption make the module easy to integrate into portable device like PNDs, mobile phones ,cameras and vehicle navigation systems.
