Sonardyne Lodestar GyroUSBL
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
Description
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.
