GyroiUSBL is ideal for short, long term installations and long layback tracking. It combines our 6th (6G®) generation high performance HPT Inverted USBL transceiver and a Lodestar Attitude and Heading Reference System (AHRS) / Inertial Navigation System (INS) in the same titanium pressure rated mechanical assembly capable of operating at depths of 7000 m.

With the AHRS / INS in fixed mechanical alignment to the iUSBL’s pressure balanced acoustic array, the GyroiUSBL can be quickly deployed without need for a calibration to determine the alignment of the ship’s motion sensors to the acoustic transceiver. For many applications, this can enable significant time savings and operational costs.
