Subsonus
Subsonus is an advanced USBL (ultra-short baseline) underwater acoustic positioning system that combines a sophisticated eight-channel hydrophone array with an integrated and tightly-coupled INS. Featuring adaptive transmit power and excellent multipath performance, it fuses acoustic position and Doppler velocity with inertial outputs and depth sensor data, providing highly accurate position, velocity and heading.
The miniature USBL can operate at depths of down to 1000 metres, and is ideal for marine platform stabilization and station-keeping, and underwater survey AUVs and ROVs.
