NMEA0183 Format
The GXB5005 can output 8 different types of sentence: GPGGA, GPGLL, GPGSA, GPGSV, GPRMC, GPVTG,
GPZDA and PSGSA. If 9600bps, 19200bps or 38400bps baud rate is set for port setting, it outputs 7 types of
sentence: GPGGA, GPGSA, GPGSV, GPRMC, GPVTG, GPZDA and PSGSA as default. Moreover, if 4800bps
baud rate is set, it outputs 4 types of sentences: GPGGA, GPGSA, GPGSV and GPRMC as default.
NMEA Message Output Timing
NMEA messages are output within 1s after the 1PPS pulse.
