File of satellite messages GPS (NMEA 0183)

 Previous Top

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.

$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.
