CSC turns off all output except the GPGGA sentence. The timerequired to output a NMEA sentence can be determined by multiplying themaximum number of characters by 10 then dividing the result by the baud rate.Selected sentences will be transmitted at a periodic rate based on the selectedbaud rate and the selected output sentences. The sentences will be outputcontiguously. Regardless of the baud rate, the sentences are reference to thePPS signal immediately preceding the GPRMC sentence, or whicheversentence is output first.TABLE D-4. $GPGGA Global Positioning System Fix Data$GPGGA,1,2,3,4,5,6,7,8,9,M,10,M,11,12*hhCRLF<1> UTC time of position fix, hhmmss format<2> Latitude, ddmm.mmmm format (leading zeros will be transmitted)(5 digits of precision on GPS 16A)<3> Latitude hemisphere, N or S<4> Longitude, ddmm.mmmm format (leading zeros will betransmitted) (5 digits of precision on GPS 16A)<5> Longitude hemisphere, E or W<6> GPS quality indication, 0 = fix not available, 1 = Non-differentialGPS fix available, 2 = Differential GPS (DGPS) fix available, 6 =Estimated<7> Number of satellites in use, 00 to 12 (leading zeros will betransmitted)<8> Horizontal dilution of precision, 0.5 to 99.9<9> Antenna height above/below mean sea level, -9999.9 to 99999.9meters<10> Geoidal height, -999.9 to 9999.9 meters<11> Differential GPS (RTCM SC-104) data age, number of secondssince last valid RTCM transmission (null if not an RTCM DGPSfix)<12> Differential Reference Station ID, 0000 to 1023 (leading zeros willbe transmitted, null if not an RTCM DGPS fix)D-3
