Micro-Ranger 2 is an acoustic positioning system for tracking divers, remotely operated and autonomous underwater vehicles. Portable and quick to mobilize, Micro-Ranger 2 can be deployed from any waterside location or vessel of opportunity, including RHIBs and small survey vessels. This makes it ideal for supporting marine operations conducted in rivers, lakes and coastal waters. The system has an operating range of 995 meters and can update the position of each target being tracked up to twice a second.
The Nano Transponder connector-less design is recharged and programmed via the Nano Docking Station. It takes around 12 hours to fully recharge the high capacity battery. The standard instrument is depth rated to 500 m (300 m with pressure sensor) and has an acoustic source level and beam shape that is designed to operate over a 750 m slant range under normal conditions. The Nano Transponder operates in the Medium Frequency (MF) band so it is compatible with Sonardyne's Mini-Ranger 2 6G Wideband USBL system.
