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. 6G® systems offer precise acoustic ranging, fast data telemetry and hardware that is easier to set up and operate even in the most challenging subsea operating environments. These features improve the efficiency of survey operations, reduce vessel delays and generate cost savings for owners.
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. One second position updates are achievable in any water depth.
Ranger 2 Pro is designed for complex operations where any number of subsea targets can be tracked. Multiple transceivers and attitude compensation sensors canbe simultaneously interfaced into Ranger 2 Pro allowing for highly redundant, bespoke installations. Ranger 2 Pro also supports subsea INS integration, external triggers foracoustic synchronisation and user configurable displays.
