5. Open
Positioning
tab and set the Elevation
mask to 15 degrees .

6. To set up the base station, open the
Base
tab and
set the following parameters: Antenna Phase Center
Position (APC)
- enter latitude, longitude, and altitude
(ellipsoidal height) values of the antenna position. Do
one of the following:
• If known, type in the values.
• Click Get from receiver to use the current antenna
position.
7. Restart your receiver. Open the
Base
tab and
check coordinates. Click Refresh , to refresh the pa-
rameters.

the
Position Computation Mode
- this drop-down list
box allows selecting the mode of position computa-
tion:
• pd -carrier phase differential (RTK) with fixed
ambiguities
• pf - carrier phase differential (RTK) with float am-
biguities
• cd- code differential (DGPS) mode
• wd - wide area code differential mode (WDGPS)
• sp - single point positioning mode1
Open the Rover tab and set up the following pa-
rameters:
• RTK Position Computation Mode – se-
lect Extrapolation for RTK float (kine-
matic), or Delay for RTK fixed (static).
If Extrapolation is selected, the rover will extrapo-
late 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 po-
sition (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).
• Confidence Level for Ambiguity – list box governs
the process of the RTK engine fixing integer ambi-
guities. The RTK engine uses the ambiguity fix indi-
cator when making a decision whether to fix ambi-
guities or not. Low, Medium and High correspond
