Sonardyne Ranger 2 Pro is a survey grade Ultra-Short BaseLine (USBL) acoustic positioning system. I delivers in standard and Pro form. Designed for deep water, long range tracking of underwater targets and position referencing for dynamically positioned 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.
Two versions of Sonardyne Ranger 2 USBL are available; Standard and Pro. In Standard configuration Ranger 2 allows multiple subsea targets to be simultaneously tracked from a surface vessel at ranges of 6000 metres and beyond. It is compatible with all makes of dynamically positioned system and can achieve one second position updates in any water depth.
