ALSEAMAR designs and manufactures portable trajectography systems for devices moving under water, torpedoes or drones, under the GIB product line.
Consisting of a control unit and a set of buoys, they receive the signals transmitted by the acoustic transmitter mounted on the underwater device being tracked. The buoys measure distances and use a local radio network to periodically transmit 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 underwater device and displays them on a map in real time and with great precision.
GIB portable trajectography systems are used by manufacturers in the naval sector to qualify their subsea machinery and by naval forces to train their crews and to intervene in the event of a stricken submarine in order to accurately locate it.
