Ranger 2 is a high performance acoustic susbea positioning reference system designed for tracking underwater targets and positioning dynamically positioned (DP) vessels. The system (commonly referred to as a HPR system) uses the Ultra-Short BaseLine (USBL) positioning method to calculate 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.

Version 4 Software 

Version 4 of Ranger 2 USBL system software is now available.This major release includes many capability,productivity and usability improvements such as a revised Navigation Chart for Windows 7, support for iWAND and a new Beacon Wizard with integrated 6G Discovery.

Discovery mode automatically detects previously deployed transponders including their configured address and channel.Positions can now be displayed in Latitude/Longitude or US Survey Feet,and for DP users there is a new Array Planning tool,as well as Vessel Reference Points with Watch Circles.
