• RTK Parameters , RTK mode – select 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.
This setting (extrapolation) is recommended.
– Delay is for 1 Hz high precision RTK applications. The
Rover RTK engine computes 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).
• RTK Parameters , Dynamics – select Static or Kinematic.
• RTK Parameters , Ambiguity fixing level – (not applicable to
RTK Float) select either Low, Medium, or High for indicator
states of 95%, 99.5%, or 99.9%, respectively. The RTK
engine uses the ambiguity fix indicator when making
decisions whether or not to fix ambiguities. The higher the
specified confidence level, the longer the integer ambiguity
search time.
