GS2 Display—RTK
OUO6050,0000C20 –19–17OCT07–2/2
NOTE: If communication loss is WITHIN first hour of
base station operation, Extend Mode will
provide RTK accuracy for two minutes.
Communication loss AFTER first hour of base
station operation, Extend Mode will provide
RTK accuracy for 15 minutes.
Extend Mode (RTK-X)
If communication between base station and vehicle
radio is lost for more than 10 seconds, vehicle receiver
will automatically switch to Extend Mode and will
maintain RTK accuracy for a period of time. If base
station has been powered for less than one hour,
Extend Mode will be available for 2 minutes. If base
station receiver has been powered for more than one
hour, 15 minutes of Extend Mode will be available. If
base station communication is not re-established after
Extend period, receiver will default to EGNOS, or NO
DIFF where EGNOS is not available. To re-establish
communication move vehicle to a location where line
of sight to base station can be established.
