Gyro USBL combines a Sonardyne 6th (6G®) generation high performance HPT USBL transceiver and a Lodestar Attitude and Heading Reference System (AHRS) / Inertial Navigation System (INS) in the same mechanical assembly.
With the AHRS / INS in fixed mechanical alignment to the USBL’s acoustic array, and ‘in-water’ pre calibrated at the factory, Gyro USBL can be quickly deployed without need for a USBL calibration. This enables significant savings in vessel time and operational costs. Depending on the array type, Gyro USBL can offer precision of better than 0.1% of slant range out of the box.
Manufactured in alumininum bronze, the Gyro USBL is ideally suited for installations on vessels of opportunity using through-hull or over-the-side poles. It is also ideal for permanent installation on flexible stem tubes and on very small vessels such as USVs.
