Ranger 2 from Sonardyne is a sixth-generation (6G) ultra-short baseline (USBL) underwater positioning system. It offers a standard operating range of up to 7,000 metres and the ability to simultaneously track up to 99 subsea targets (eg sidescan sonars, ROTVs, ROVs and structures) at very fast update rates. Supports all industry standard DP telegrams and acoustically aided INS.

Sonardyne Ranger 2 USBL comprises of the navigation sensor hub (NSH), a topside PC, Ranger 2 software, the HPT 5000 transceiver and an installation kit.

HPT 5000 transceiver

At the heart of Ranger 2 is the HPT (high performance transceiver) 5000 transceiver.

The HPT 5000 is an acoustic and telemetry transceiver designed for use with Ranger 2 USBL and Marksman LUSBL systems. HPT 5000 enables targets offer wide range of water depths to be tracked. The unit is highly versatile and can be deployed other-the-side, through-tube or through-hull.

HPT 5000 offers full hemispherical acoustic coverage so it is a popular choice for tracking multiple targets (ROVs, AUVs, towfish, seafloor sensors) over a wide range of depths and elevations. The unit is also suitable for dynamic positioning reference on survey, research and offshore support vessels.

The transceiver fully supports 6G LBL operations using Fusion 2 LBL software. It is also a highly capable acoustic communications modems, able to interrogate, command and recover data payloads from deployed Sonardyne instruments including AMTs and Fetch. By supporting telemetry rates of up to 9000 bps, it minimises the time a vessel has to wait on location to recover data – and supports LBL operations.

Compatible with WSM 6+ Omni and Directional Transponders.
