Adjust the following RTK Parameters settings:
• Under RTK mode in the RTK Parameters section, choose
either Extrapolation for RTK float (kinematic) or Delay for
RTK fixed (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,
