A long-range subsea target tracking and DP reference system for deep water operations, supporting unlimited targets with up to 6,000 meters range.
The Sonardyne Ranger 2 is a survey-grade Ultra-Short Baseline (USBL) acoustic positioning system designed for deep water, long-range tracking of underwater targets such as ROVs, towfish, and AUVs. It serves as a position reference for dynamically positioned (DP) vessels by calculating the position of subsea targets through range and bearing measurements from vessel-mounted transceivers to target transponders.
The system is available in two versions: the standard configuration tracks up to 10 simultaneous subsea targets, while the Ranger 2 Pro version supports tracking an unlimited number of targets with features like multiple transceiver interfacing and subsea INS integration. The system utilizes Sonardyne's Wideband 2 signal architecture for precise ranging and fast data telemetry.
