Bcd996t Gps Command Data Formats
Here is the two NEMA GPS data formats used by the Unit for anyone who might want to know what data it contains.
GGA GPS FORMAT
GGA,hhmmss.ss,1111.11,a,yyyyy.yy,a,x,xx,x.x,x.x,M,x.x,M,x.x,xxxx*hh
1 UTC of Position
2-3 Latitude - N/S
4-5 Longitude - E/W
6 GPS Quality Indicator
0 = fix not available or invalid
1 = GPS SPS Mode, Fix valid
2 = Differential GPS, SPS Mode, fix valid
3 = GPS PPS Mode, fix valid
7 Number of satellites in use (00-12, may be different
from the number in view)
8 Horizontal dilution of precision
9 Antenna altitude above/below mean sea level
10 Units of antenna altitude, meters
11 Geoidal separation - difference between the WGS-84
earth ellipsoid and mean sea level (geoid), “-” =
mean sea level below ellipsoid
12 Units of geoidal separation, meters.
13 Age of Differential GPS data - Time in seconds since
last SC104 Type 1 or 9 update, null field when DGPS
is not used
14 Differential reference station ID, 0000-1023
RMC GPS FORMAT
RMC,hhmmss.ss,A,1111.11,a,yyyyy.yy,a,x.x,x.x,xxxxxx,x.x,aa*hh
1 Time, UTC of position fix
2 Status (A = valid, V = Navigation receiver warning)
3-4 Latitude at UTC time, N or S
5-6 Longitude at UTC time, E or W
7 Speed over ground, knots
8 Course over ground, degrees
9 Date (DDMMYY)
10 Magnetic variation, degrees (E or W)
11 Mode Indicator
The formats listed are NMEA formats
