NORBIT Security recently conducted a test with the Armed Forces of a NATO country to test the capability of GuardPoint Tracking Software interfaced with WBMS FLS sonar.
The test was carried out in very shallow waters of a river where depth is only between 1 and 2m with a visibility of only 5 to 10cm. The use of WBMS FLS was preferred because of the shallow water conditions.
