Surveying with the Maxor
3. Click Configuration->Receiver .
4. Select the Positioning tab and set the Position Masks, Elevation mask (degrees)
parameter to 15 (Figure 3-10 on page 3-13).
5. Select the Rover tab and set the desired Positioning Mode (Figure 3-13).

Adjust the following RTK Parameters settings:
•
Under RTK mode in the RTK Parameters section, choose either Extrapolation for
RTK (kinematic) or Delay for RTK (static).
–Extrapolation is for low-latency, high frequency output (>= 5 Hz) RTK
applications. The rover will extrapolate the base station's carrier phase
measurement corrections when computing the rover's current RTK position.
–Delay is for 1 Hz high precision RTK applications. The Rover 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).
•
Select the antenna status during RTK, either Static or Kinematic.
• Specify the Ambiguity fixing level (not applicable to RTK Float). The Ambiguity
Fixing Level radio buttons govern the process of the RTK engine, fixing integer
ambiguities. The RTK engine uses the ambiguity fix indicator when making
decisions whether or not to fix ambiguities. Low, Medium, and High correspond
to the indicator's 95%, 99.5% and 99.9% states, respectively. The higher the
specified confidence level, the longer the integer ambiguity search time.
6. Select the Ports tab and set the following parameters for Serial C (Figure 3-14 on
page 3-17):
• Input drop-down list – select desired differential correction format.
•
Period (sec) – leave as is.
