Figure 29. NAVconfig output smoothing properties window
The smoothing of the position, velocity and orientation corrections can be controlled
independently. Enter the maximum correction that can be applied every second. For
example, if 0.1 m is entered for the position smoothing then the will only correct
a position error by a maximum rate of 0.1 m/s.
If a large error is accumulated (for example, if GNSS is not available for a long period of
time) then it may take a very long time to apply the correction. Under these circumstances
it may be preferable to “jump” the measurement to the correct value quickly. By specifying
a time in the
Time limit
section for the correction, the will jump the measurement
if it will take too long to correct.
Care should be taken not to make the smoothing too small. If these parameters are
inappropriate, then the will not be able to make suitable corrections to the outputs
and it will not work correctly.
Note: this function is designed to improve the data in real time. When post-processing the
data using the forwards-backwards combined option, output smoothing should not be used
as it may give unexpected results.
