network that is closest to the rover. The corrections
from that reference is sent to the rover. Supported for
all real-time data formats.
If this option is selected, a NMEA GGA message
must be activated using GGA (F4). Refer to "22.3.7
Configuration of GGA Message Sending for Refer-

individualised Master-AuXiliary corrections.
The rover sends its position via NMEA GGA message
to LEICA GPS Spider where the Master-Auxiliary
corrections are calculated. The corrections are also
individualsied by LEICA GPS Spider, which means it
determines the best suitable corrections for that
rover.
The corrections are sent in Leica, RTCM v2.3 or
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
