Ranger 2 USBL is a precision, surveygrade Ultra-Short BaseLine (USBL) acoustic positioning system designed for Dynamic Positioning (DP) reference and for ROV/towfish tracking operations, primarily for construction and survey use. Ranger2 builds on the simplicity and reliability of Ranger 1, but adds support for new Sonardyne 6G® instruments and Wideband 2 acoustic signals. Ranger 2 can track up to ten targets simultaneously to ranges of greater than 6,000 metres. The system supports all industry standard telegrams and is compatible with a wide range of transponders including Sonardyne’s Compatt 6, Compatt 5, Wideband Sub-Mini beacons and responders as well as Kongsberg HPR. Ranger 2 software has an extensive set of tools to allow the user to optimise the system performance, including real-time acoustic quality indicators, as well as traditional signal and noise analysis and travel time displays. Sonardyne’s CASIUS calibration tool is also included to correctly calibrate gyro and VRU offsets, and so improve positioning accuracy. With the addition of a co-located Lodestar AHRS to a 6G® USBL transceiver, perfect timesynchronisation is achieved, giving the optimum solution for deep water DP and construction survey.
