NMEA Message Definitions
APA Autopilot cross track error, direction to steer, status of
GPS, route status, destination waypoint name, and bear-
ing from origin to destination (old format).
APB Revised autopilot message contains all of the above plus:
heading to steer toward destination, bearing from the
present position to the destination (magnetic or true).
BWC Range and bearing to a waypoint
GGA GPS position, time, fix quality, number of satellites
used, HDOP (Horizontal Dilution of Precision), dif-
ferential reference information, and age.
GLL GPS-derived latitude, longitude, and time of fix.
GSA GPS receiver operating mode, satellites used in the navi-
gation solution reported by the $--GGA sentence and
DOP (Dilution of Precision) values.
GSV Number of satellites in view, satellite numbers, eleva-
tion, azimuth, and SNR value.
RMB Data status, cross track error, direction to steer, origin,
destination waypoint, waypoint location, bearing to
destination, and velocity toward the destination.
RMC Time, latitude, longitude, speed, heading, and date.
VTG Track (magnetic and true) and groundspeed (knots and
KPH).
NMEA Messages
Your GPS receiver can be set to output GPS data in the NMEA
0183 version 1.5 or version 2.1 format to interface with other
marine devices or equipment.
NMEA DATA MESSAGES. NMEA data is output at 4800
baud, 8, N, 1. These settings are acceptable to most equip-
ment and software applications. The baud rate can also be set
to 1200, 9600 or 19200.
There are several NMEA output message sets, each with a
slightly different application. Check documentation for your
external equipment to choose the appropriate message set.
