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 parameters.

7. To set up the rover, open 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 am-
biguities
• 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 param-
eters:
• RTK Position
lect Extrapolation
matic), or Delay
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 com-
pute the current rover position. Instead, the RTK en-
gine will compute either a delayed RTK position (for
the epoch to which the newly received RTCM/CMR
message corresponds) or the current stand-alone po-

• Confidence Level for Ambiguity – list box gov-
erns the process of the RTK engine fixing integer
ambiguities. The RTK engine uses the ambiguity fix
indicator when making a decision whether to fix am-
biguities or not. Low, Medium and High correspond
to the indicator's 95%, 99.5% and 99.9% states, re-
spectively. The higher the specified confidence lev-
el, the longer the integer ambiguity search time. This
is the price one pays for the higher reliability of the
ambiguity fixed solution.
9. For RTK survey, open the Ports tab and set up the
parameters according Table 2, then click Apply.
Note: For the survey with the post-processing keep default
parameters..
