Ranger 2 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 (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.

Two versions of 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 6,000 metres and beyond. It is compatible with all  makes of DP system and can achieve one second position updates in any water depth.
