The smart GPS compass data output conforms to the NMEA 0183 V4.0 at 4800, 9600, or 19200
baud. Below is a list of the NMEA sentences output:
NMEA 0183 data output sentences
(1) GBS - GNSS Satellite Fault Detection (Modied MX Marine version)
This message is used to support Receiver Autonomous Integrity Monitoring (RAIM) feature in
the MX CDU. A special character flag was added for proper RAIM status determination

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: 0=safe, 1=caution, 2=unsafe
10 GNSS signal ID: 0 = All, 1 = GPS
