Alcen Alseamar - Acoustic Positioning System
ALSEAMAR designs and manufactures portable trajectography systems for mobile submarine vehicles, torpedoes or drones, under the GIB product range. Consisting of a control unit and a set of buoys, they receive the signals transmitted by the acoustic transmitter mounted on the submarine being tracked. The buoys measure distances and periodically transmit, using a local radio network, their GPS position and the distances measured to a control unit installed on a support or land vehicle. This unit triangulates the positions of the subsea vehicle and displays them on a board in real time and with very great precision.
GIB portable trajectography systems are used by manufacturers in the naval sector to qualify their subsea machinery and by navies to train their crews and intervene in the event of accidents with a submarine in distress in order to locate it accurately.
