9.3.3 DESELECTING A CHANNEL FOR A USBL COMPUTATION
It is possible to exclude one channel of the USBL from the computation. In case of one faulty
hydrophone, it improves greatly the positioning accuracy to be able to perform the positioning
without this hydrophone. A faulty hydrophone may greatly decrease the quality of the
positioning.
The automatic (default) mode rejects the erroneous detections of any hydrophone when it is
the case.
1. Even during tracking, click on options in the top right corner of the application.
2. Select Hn disabled to exclude all detections made by the Hn hydrophone.
