File of satellite messages GPS (NMEA 0183) |
All commands and messages are transferred in text ASCII kind, those which concern to GPS - receivers begin from $GP, at the end of message line there should be <CR> <LF> symbols. The control sum of the current message beginning from the * divider can be specified in the last field of message. Example of messages included into gpstomap.txt text file: $GPGGA,004241.47,6138672.20,N,7408403.5,E,1,04,2.0,-0015,M,0,m,0,*31 $GPGSA,A,3,01,02,03,04,05,06,07,08,09,10,11,12,13,14,2.0,2.0,2.0,*34 $GPGSV, 3, 1,12,02,86,172,,09,62,237,,22,39,109,,27,37,401,0,*7A $GPGSV,3,2,12,17,28,050,,29,21,314,,26,18,246,,08,10,153,0,*7F $GPGSV,3,3,12,07,08,231,,10,08,043,,04,06,170,,30,00,281,0,*77 $GPGGA,004281.47,6154942.2,N,7405283.5,E,1,02,2.0,-0010,M,0,m,0,*31 $GPGGA,004361.02,6165612.2,N,7406538.5,E,1,03,2.0,-0010,M,0,m,0,*23 $GPGGA,004281.27,6168222.2,N,7410593.5,E,1,06,2.0,-0015,M,0,m,0,*43 $GPGGA,004341.33,6159322.2,N,7419633.5,E,1,04,2.0,-0015,M,0,m,0,*56 $GPGGA,004452.47,6145512.2,N,7411093.5,E,1,04,2.0,-0010,M,0,m,0,*12 $GPGGA,004461.56,6146792.2,N,7423493.5,E,1,02,2.0,-0015,M,0,m,0,*3F $GPGGA,004601.25,6168522.2,N,7427703.5,E,1,03,2.0,-0010,M,0,m,0,*42 $GPGGA,004832.31,6160062.2,N,7427183.5,E,1,04,2.0,-0005,M,0,m,0,*34 $GPGGA,004845.17,6161322.201,N,7431163.5,E,1,04,2.0,-0005,M,0,m,0,*23 $GPGGA,004961.58,6135632.2,N,7431183.5,E,1,02,2.0,-0015,M,0,m,0,*31 $GPGGA,005052.47,6151172.2,N,7434663.5,E,1,04,1.0,-0010,M,0,m,0,*5G $GPGGA,005061.56,6170677.2,N,7434983.5.0,E,1,02,2.0,-0015,M,0,m,0,*4F
$GPGGA - message contains GPS - data about position, time of the definition place, quality of data, quantity of the used satellites, the information about differential corrections and their age.
$GPGSA - In this message operating mode of GPS - receiver, satellites parameters, used at the decision of the navigating task, which results are displayed in $GPGGA message and factors values of coordinates definition accuracy are displayed.
$GPGSV - In the message the quantity of visible satellites, their numbers, height, azimuth, and signal/noise relation value for each of them are shown.
$GPGLL - Message contains GPS-data about longitude, latitude and time of coordinates definition. |
