Here in GPS mode:
VE2PRT 3,BN VIA D-RATS*47
The above is translated at the receiving end to be fed to APRS-IS as
VE2PRT-3>APDPRS,DSTAR*,qAR,VA2RKA-B:!4527.32N/07335.26W- VIA D-RATS/A=000089
In GPS mode, there is option to send $GPGGA and/or $GPRMC. Sending both
will provide both altitude, speed and course.
and here in GPS A mode:
$$CRC7647,VE2PRT-3>APRATS,DSTAR*:@141113h4527.32N/07335.26W-ve2prt at sympatico.ca
After validation, the CRC is removed and the string is passed as is
starting to APRS-IS.
When I mention "APRS-IS", it can be some remote server to redistribute
over the Internet and/or a local server to feed local APRS clients
(Xastir, UI-View, etc).
