Gyro USBL combines a Sonardyne 6th (6G®) generation High Precision Acoustic Positioning (HPT) USBL transceiver and a Lodestar Attitude and Heading Reference System (AHRS)  in the same pressure rated mechanical assembly capable of operating at ranges of 7000 m.

With the AHRS in fixed mechanical alignment to the USBL’s pressure balanced acoustic array, the Gyro USBL 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 savings time and operational costs.

Manufactured in Aluminium-Bronze the Gyro USBL is ideally suited for short term temporary installations on vessels of opportunity using through-hull or over-the-side poles. It is also ideal for permanent installation on flexible stem tubes.
