8. To set up the rover, open the
Positioning
tab and set the
Position Computation Mode
– this drop-down list box allows selecting the mode of position computation:
•
pd
-carrier phase differential (RTK) with fixed ambiguities
•
pf
- carrier phase differential (RTK) with float ambiguities
•
cd
- code differential (DGPS) mode
•
wd
- wide area code differential mode (WDGPS)
•
sp
- single point positioning mode1
9. Open the Rover tab and set up the following parameters:
•
RTK Position Computation Mode
– select
Extrapolation for RTK float
(kinematic)
, or
Delay for RTK fixed (static)
. If Extrapolation is selected, the rover
will extrapolate the base station’s carrier phase measurements when computing the
rover’s current RTK position. If Delay is selected, the rover will not extrapolate the
base station’s carrier phase measurements to compute the current rover position.
Instead, the RTK engine will compute either a delayed RTK position (for the epoch
to which the newly received RTCM/CMR message corresponds) or the current
stand-alone position (while waiting for new RTCM/CMR messages coming from the
base).
