Prediction
Height smoothing
The following provides additional information on the prediction of real-time positions between
the data rate of the reference. This can be activated for a real-time rover interface unless <R-
Time Data: RTCM 1,2 v2> or <R-Time Data: RTCM 9,2 v2>.
Access
SHIFT PRED (F3) in CONFIGURE Real-Time Mode.
Description
Prediction is the interpolation of real-time corrections between those regularly transmitted by
a reference at a defined data rate.
Advantages in using prediction
• Computation of real-time positions on the rover is independent from the transmission rate
of the data from the reference station.
• Positions computed with prediction have a reduced latency of around 20 ms.
Recommended settings for using prediction
The slower the data rate the more important it is to activate prediction.
The following provides additional information on the height filter for height smoothing. This
can be activated for a real-time rover interface unless <R-Time Data:
WAAS/EGNOS/MSAS>.
