7. About the recorded NMEA sentence for GPS logging Regarding the GPS logging data of the transceiver, each sentence corresponds to the NMEA standard and is recorded in the following format. D GGA sentence (e.g.) $GPGGA,161229.487,3723.2475,N,12158.3416,W,1,07,1.0,9.0,M,25.5,M,3,0000*18 q w e r yu i t o !0 !1 !2 q GGA protocol header ($GPGGA) w UTC of position (16:12:29.487) e Latitude (North 37º 23.2475′) N=North, S=South r Longitude (West 121º 58.3416′) E=East, W=West t GPS quality indicator (1) 0=Fix not available or invalid, 1=SPS mode 2=DGPS (SPS), 6=Estimated (Dead Reckoning) mode y Number of satellites in use (7), 00-12 u Horizontal Dilution of Precision (1.0) 0.0-50.0 i Altitude re: mean-sea-level (geoid), meters (9.0 meters) o Geoidal separation, meters (25.5 meters) !0 Age of Differential GPS data (3 seconds) !1 Check Sum (*18) Error detection data started with "*" (hex code) !2 End code *Blank shows when not positioned. D RMC sentence (e.g.) $GPRMC,161229.487,A,3723.2475,N,12158.3416,W,0.13,309.62,311120, , ,D*10 q w r e t yu i !0 !1 o q RMC protocol header ($GPRMC or $GNRMC*) * When both the GPS and GLONASS satellites are used. w UTC of position (16:12:29.487) e Status (A) A=Data valid V=Data invalid/not positioned r Latitude (North 37º 23.2475′) N=North, S=South t Longitude (West 121º 58.3416′) E=East, W=West y Speed over ground (0.13 knots) u Course Over Ground (309.62º; degrees True) 0.00º-359.99º i UTC date of position ('20 Nov 31st) ddmmyy o Mode Indicator (D) A=Autonomous mode, D=DGPS, E=Estimated (dead reckoning) mode, N=Data not valid, R=Almanac data !0 Check Sum (*10) Error detection data started with "*" (hex code) !1 End code *Blank shows when not positioned.
