Sonardyne Gyro USBL: Pre-calibrated USBL and telemetry transceiver

Sonardyne's second-generation Gyro USBL transceiver – lighter, smaller, and equally capable. This advanced device seamlessly collaborates with Ranger 2 to track the position of subsea targets from various platforms such as USVs, vessels of opportunity, or pipelay vessels' stingers over extensive ranges. The Gyro USBL ensures the highest precision available and comes pre-calibrated directly from us, saving you valuable operational time.

Specifically designed for compatibility with Ranger 2, Gyro USBL is an all-in-one instrument that integrates our 6th generation (6G) High Precision Acoustic Positioning (HPT) acoustic transceiver and Lodestar Attitude and Heading Reference System (AHRS) into a single unit. This innovative combination eliminates alignment errors typically observed in conventional USBL systems, as it is not reliant on a vessel's own attitude and heading sensors. Experience precision and efficiency with Gyro USBL, enhancing your subsea tracking capabilities.
