Ranger 2 is a survey grade Ultra-Short BaseLine (USBL) acoustic positioning system designed for deep water, long range tracking of underwater targets and position referencing for dynamically positioned (DP) vessels. The system calculates the position of a subsea target, for example an ROV, by measuring the range and bearing from a vessel-mounted transceiver to an acoustic transponder fitted to the target. Multiple subsea targets over a wide area and range of water depths can be simultaneously and precisely positioned.
Ranger 2 builds on the simplicity and reliability of Sonardyne’s original Ranger system but adds support for the latest 6G® (Sixth Generation) acoustic instruments and Wideband 2 signal architecture.
Ranger 2 is available in two versions. In standard configuration, Ranger 2 allows up to 10 subsea targets to be simultaneously tracked from a surface vessel. Operating ranges of greater than 6,000 metres are achievable and the system supports a widerange of industry standard survey and DP output telegrams.
