Inverted USBL transceiver with gyro
Engineered for: AUV, Towfish
Gyro iUSBL turns a conventional USBL setup on its head. It combines a USBL transceiver and AHRS in a single subsea housing, and is designed to be mounted on a towed body so it can be tracked at laybacks in excess of 10,000 m.
Built for deep, long layback tracking

Gyro iUSBL combines our 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 Gyro iUSBL 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.
