For RTK Extend to achieve maximum
performance, the rover must be fully converged,
which typically requires one (1) hour of
operation.
The correlation between RTK and StarFire
phase measurement corrections decreases over
time, until the system automatically transitions
out of RTK Extend mode to the next available
dGPS mode.
This option is only required on the Rover
receiver. If a Base receiver may be used as a
Rover at a future date, it should be optioned for
RTK Extend as well. Refer to the StarUtil 3000
User Guide, Chapter 5, for more information on
RTK Extend.
