Use these commands to define/inquire the code measurement smoothing interval.
The
Interval
argument defines the length of the smoothing filter that is used to smooth the
code measurements by the carrier phase measurements. It is possible to define a different
interval for each signal type. If
Interval
is set to 0, the code measurements are not smoothed.
The smoothing interval can vary from 1 to 1000 seconds.
To prevent transient effect from perturbing the smoothing filter, smoothing is disabled
during the first ten seconds of tracking, i.e. when the lock time is lower than 10s.
Likewise, the smoothing effectively starts with a delay of 10 seconds after entering the
command.
Code smoothing allows reducing the pseudoranges noise and multipath. It has no influence
on the carrier phase and Doppler measurements. The smoothing filter has an incremental
effect; the noise of the filtered pseudoranges will decrease over time and reach its minimum
after
Interval
seconds. For some applications, it may be necessary to wait until this transient
effect is over before including the measurement in the PVT computation. This is the purpose
of the
Alignment
argument. If
Alignment
is not set to 0, measurements taken during the first
Alignment
+10 seconds of tracking will be discarded. The effective amount of
Alignment
is
never larger than
Interval
, even if the user sets it to a larger value.
