Lodestar GyroUSBL 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.
The instrument comes in three mechanical variants; two standard GyroUSBLs that differ by the use of the HPT component (GyroUSBL 8084-000-0445 and 8084-000-0447) and one inverted version (GyroiUSBL 8084-000-7535).
With the AHRS / INS in fixed mechanical alignment to the USBL’s acoustic array, the Lodestar GyroUSBL can be quickly deployed without need for a USBL calibration to determine the alignment of the ship’s motion sensors to the acoustic transceiver. For certain applications, this can enable significant savings in vessel time and operational costs.
The HPT transceiver component of the instrument utilises the latest Sonardyne Wideband®2 signal processing and is fully compatible with other products in the new Sonardyne 6G® equipment range.
Lodestar is tightly integrated into the USBL system providing power and communications to the HPT transceiver and embedded highly accurate time-stamping of all motion and acoustic data. This enables unparalleled precision and accuracy of position estimation by removing many of the sources of error associated with all USBLs such as lever arm offsets, pole bending, and ship flexing.
