The study of the float buoy ranging system for the underwater vehicle

The float buoy ranging system consists of a vessel-mounted pinger, three surveying float buoys which receive the pinger signal and the receiving station on the testing ship. The antenna of the receiving station receives the radio signal for the underwater vehicle's position from three surveying float buoys. At the same time it receives the radio signals for three float buoy's position an the surface of the sea from four GPS satellites. The surveying float buoy processing system in the receiving station tracks down the running locus of the underwater vehicle as the X-Y co-ordinates from the values of the latitude and the longitude. Further, it is possible to carry out the float buoy ranging system's calibration to determine the float buoy position at any time.
