Ranger 2 USBL

The system is made up of software, a vessel-mounted transceiver and in-water transponders. The transceiver is available in a range of different designs to suit operational needs; deep, shallow and long layback.

Ranger 2 comes with Sonardyne’s 6G (sixth generation) acoustic hardware platform and Sonardyne Wideband 2 digital signal architecture to provide stable and repeatable acoustic position referencing for a ship’s DP system.

It also supports robust two-way data telemetry allowing users to command a range of seafloor deployed long-endurance sensors and recover the logged data inside them.

Key features:

  • Tracks multiple targets to 11 km; ROVs, AUVs, deep towed bodies
  • Compatible with all makes of DP system – GE, Kongsberg, MT
  • System accuracy: when fully optimized it will deliver 0.04% of slant range
  • Works with a global inventory of pre-deployed Sonardyne 6G hardware
  • Configurations available for USV and temporary vessel installations
