Below is a list of the NMEA sentences output:
NMEA 0183 data output sentences
(1) GBS - GNSS Satellite Fault Detection (Modified MX Marine version)
This message is used to support Receiver Autonomous Integrity Monitoring (RAIM) feature in
the MX420 CDU. A special character flag was added for proper RAIM status determination
$PMVXG,GBS,hhmmss.ss,x.x,x.x,x.x,xx,x.x,x.x,x.x,x*hh<CR><LF>
1 2 3 4 5 6 7 8 9
¼ Notes:
1 UTC time of the GGA or GNS fix associated with this sentence.
2 Expected error in Latitude (meters)
3 Expected error in Longitude (meters)
4 Expected error in Altitude (meters)
5 ID number of most likely failed satellite
6 Probability of missed detection for most likely failed satellite
7 Estimate of bias in meters on most likely failed satellite
8 Standard deviation of bias estimate
9 RAIM status mode; 0=safe, 1=caution, 2=unsafe
(2) GGA – Global Positioning System Fix Data
Time, position and fix related data for a GPS receiver.
