27.5 NMEA OUT Serial Data Formats
NMEA output data consists of industry standard NMEA 0183 Version v4.00 sentences. A
reference for Version 4.00 of the standard can be found here:
www.nmea.org/content/nmea_standards/nmea_083_v_400.asp
27.5.1 NMEA OUT (BASIC)
NMEA OUT (BASIC) serial output data consists of GGA, GSA, GSV, RMC, and VTG
sentences nominally output at a rate of 1 Hz. The rate is reduced if necessary to transmit
the entire set of data at the selected baud rate. This format outputs GPS data for position,
speed, altitude, and heading.
For example, the following is one (1) cycle of NMEA OUT (BASIC) serial output data:
$GPGGA,214921,3121.6199,N,00000.0000,E,1,04,1.90,3000.0,M,33.9,M,,0000*62
$GPGSA,A,3,01,02,03,04,00,00,00,00,00,00,00,00,1.00,1.90,1.90*07
$GPGSV,1,1,04,01,20,100,10,02,30,200,56,03,45,300,32,04,62,045,05*7A
$GPRMC,214921,A,3121.6199,N,00000.0000,E,82.07,1.00,300811,0.51,W,A*01
$GPVTG,1.00,T,0.51,M,82.07,N,151.99,K,A*1E
27.5.2 NMEA OUT (FULL)
NMEA OUT (FULL) data consists of all of the NMEA OUT (BASIC) sentences followed
by RMB, GLL, BWC, XTE, BOD, and APB sentences nominally output at a rate of 1 Hz.
The rate is reduced if necessary to transmit the entire set of data at the selected baud
rate. This format outputs navigation information derived by SkyView, and is similar to the
output that many handheld portable aviation GPS navigators generate.
For example, the following is one (1) cycle of NMEA OUT (FULL) serial output data:
$GPGGA,221755,3157.4430,N,00000.0000,E,1,04,1.30,3000.0,M,33.9,M,,0000*66
$GPGSA,A,3,01,02,03,04,00,00,00,00,00,00,00,00,1.00,1.30,1.40*00
$GPGSV,1,1,04,01,20,100,10,02,30,200,56,03,45,300,32,04,62,045,05*7A
$GPRMC,221755,A,3157.4430,N,00000.0000,E,82.07,1.00,300811,0.49,W,A*06
