NMEA-0183 message: PTNL,AVR
Time, yaw, tilt/roll, range for moving baseline RTK
The heading computation in this message is computed from the moving baseline vector, which requires a two-antenna system.
An example of the PTNL,AVR message string is:
$PTNL,AVR,212405.20,+52.1531,Yaw,-0.0806,Tilt,,,12.575,3,1.4,16*39
                                                            
$PTNL,AVR,212604.30,+52.1800,Yaw,,,-0.0807,Roll,12.579,3,1.4,16*21
