Sonardyne Ranger 2: USBL Acoustic Positioning System
Ranger 2 is a survey grade Ultra-Short BaseLine (USBL) acoustic positioning system which 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.
Features
Simultaneously tracks multiple subsea targets; ROVs, towfish, AUVs
Compatible with all DP systems
Operating range beyond 6,000 metres
0.1% system accuracy when optimised
Up to 1 second position updates
Automated setup reduces delays
Specifications
Number of Targets Tracked: 1 surface, multiple simultaneous subsea
Operating Range: 6,000 meters
Position Update Rate: 1 second, independent of water depth
Output Telegrams: Supports all industry standard survey and DP telegrams
Applications
Designed for deep water, long range tracking of underwater targets
Position referencing for dynamically positioned (DP) vessels
Subsea structure tracking
Site survey and characterisation
