What you need to know

The perfect Ranger 2 transceiver for vessels-of-opportunity
Transceiver and Lodestar AHRS in one instrument
Can be pre-calibrated for rapid installation and comissioning
Compatible with through-hull, over-the-side and stem tube deployment pole

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.

Note 1. The The absolute accuracy of the system is dependent upon the quality of attitude and heading sensors, beacon source level, vessel noise, water depth, mechanical rigidity of the transceiver deployment machine and proper calibration of the total system using CASIUS.

*TEE – WBv2+ signals are 4x the duration of Sonardyne tone signals (WBv1 & WBv2 are 2x). The TEE figure shows the operational performance when comparing wideband and tone systems.
