NMEA-0183 message: PTNL,BPQ
Base station position and quality indicator
This message describes the base station position and its quality. It is used when the moving base antenna position and quality are required on one serial port (along with a heading message) from a receiver in heading mode.
An example of the PTNL,BPQ message string is:
$PTNL,BPQ,224445.06,021207,3723.09383914,N,12200.32620132,W,EHT-5.923,M,5*
