Description
Master-AuXiliary corrections
The rover typically does not send its position to
LEICA GPS Spider. LEICA GPS Spider calculates
and sends Master-Auxiliary corrections to the rover.
The rover individualises the corrections for its posi-
tion, which means it determines the best suitable
corrections. The corrections are sent in RTCM v3 with
message types 1015/1016.
If this option is selected, a NMEA GGA message can
be activated using GGA (F4). Refer to "22.3.7 Config-
uration of GGA Message Sending for Reference
Network Applications".
