GPS Receiver Technical Specifications

The GPS receiver COM port is turned off by default. The COM port is 5, defaults are 9600 baud, 8 bits, no parity, 1 stop bit.
COM5 default baud rate is 4800 for NMEA communication. GPS COM settings are stored in the registry.
Frequency Band
Channel bandwidth is 2 MHz. Frequency band is 1574.42 GHz to 1576.42 GHz.
Serial Interface
The GPS module supports serial interface for data communication. Transmission (TX) and Reception (RX) signals are
implemented to send commands and to receive GPS data. UART B on the module is used for communication.
The default baud rate for the NMEA 0183 protocol is 9600 bps, 8 bits, Parity None, 1 Stop. The baud rate can be increased to
115Kbps.
Accuracy
Position to within 10 meters, 2D Root Mean Square (RMS) and 5 meters 2D RMS, Satellite Based Augmentation System
(SBAS) corrected.
Velocity to within 24 meters per second.
SBAS is compatible with the Wide Area Augmentation System (WAAS) satellite signal augmenter (United States) and the
EGNOS satellite signal augmenter (Europe).
Protocol
The module outputs the following messages:
GGA - GPS Fix Data
l
RMS - Recommended Minimum Specific GPS Data
l
GSA - GPS DOP and Active Satellites
l
GSV - GPS Satellites in View
l
GLL - Geographic Position Latitude/Longitude
l
VTG - Course over Ground and Ground Speed.
l
The GPS module supports NMEA 0183 protocol and SiRF Binary Protocol.
