9.17 Message Type 100, Trimble proprietary TAIP PV message
This is the standard TAIP PV response message of format:
>RPVAAAAASBBCCCCCSDDDEEEEEFFFGGGHI<
Where:
AAAAA is the GPS time in seconds
S is + or –
SBBCCCCC is the Latitude in degrees and decimal degrees
SDDDEEEEE is the Longitude in degrees and decimal degrees
FFF is the speed in mph
GGG is the heading in degrees
H is the fix mode: 0 = 2D, 1 = 3D, 9 = no fix available
I is the data age: 2 = <10sec, 1 = >10sec, 0 = not available
Example:
>RPV81854+4902565+1220996700000012<
