Ranger USBL is the latest addition to the Sonardyne Ultra-Short Baseline product family and designed for survey and Dynamic Positioning (DP) reference operations. The system provides an operating range of up to 4,000 metres and is ideal for operators with limited experience or who are unlikely to ever undertake advanced USBL positioning and tracking tasks.

An important feature of Ranger USBL is the intuitive user interface means that the system is easy to learn, set-up and operate ensuring that any operator will achieve immediate success.

Two versions of the system are available; Ranger and Ranger Pro. Ranger is designed for DP reference and general target tracking of ROVs and towfish. Up to 4 targets can be tracked simultaneously to ranges of 2,000 metres. The system is compatible with Sonardyne's WSM, DPT and Compatt 5 range of Wideband transponders.

Range Pro is designed for more advanced survey applications. Incorporating Sonardyne's unique 'ping stacking' technology, the system offers fast position update rates (1 second independent of water depth), tracking of up to 10 targets and full ocean depth operating range (4,000 metres). Range Pro also supports a wide range of industry standard (Sonardyne and non-Sonardyne) MF frequency transponders.

A feature available in both Ranger and Ranger Pro is the ability to undertake Inverted USBL (iUSBL) tracking of towfish over super-long laybacks. With this new method, the transceiver is not installed on the vessel but on the towed body itself which is often several kilometres behind and below the ship. Mounting the transceiver in this way eliminates the need for repeated system calibration, whilst the accuracy and repeatability of the acoustic signals are improved, as the transceiver is located in a low noise, dynamically stable environment.
