$GPGGA,121505,4807.038,N,01131.324,E,1,08,0.9,133.4,M,46.9,M, , *42

where:

- $GPGGA is the NMEA 0183 sentence ID for the GPS fix data.
- 121505 is the fix taken at 12:15:05 UTC.
- 4807.038,N is latitude 48° 07.038' N.
- 01131.324,E is longitude 11° 31.324' E. 1 is the fix quality.
- The fix quality can have a value between 0 and 3, defined as follows:o0 = no fix
--1 = GPS or standard positioning service (SPS) fix
--2 = DGPS fix
--3 = Precise positioning service (PPS) fix

- 08 is the number of satellites being tracked.
- 0.9 is the horizontal dilution of position (HDOP).
- 133.4,M is the altitude, in meters, above mean sea level.
- 46.9,M is the height of the geoid (mean sea level) above the WGS84 ellipsoid.
- (empty field) is the time in seconds since the last DGPS update.
- (empty field) is the DGPS station ID number.
- *42 is the checksum field.
