Sonardyne Micro-Ranger 2 USBL


Portable and quick to mobilise, the Micro-Ranger 2 USBL can be used from any waterside location or vessel, including RHIBs and small survey vessels to track divers, underwater vehicles and equipment.

It’s built around market-leading 6G hardware and Wideband 2 digital acoustic technology.

If you’re a first time user of USBL technology, you’ll find Micro-Ranger 2 incredibly easy to use. Simply connect your computer, external GPS and transceiver to the system’s 1U-high interface unit, then attach a transponder (Nano or WSM 6+) to each target you want to monitor the position of. With the transceiver lowered into the water, you’re ready to start tracking up to 10 targets, sequentially and up to ranges of 995 metres.

The Micro-Ranger transceiver (MRT) is extremely small and light and can be deployed from the side of a vessel, pontoon using its cable, or on the sensor spar of a USV. Its design provides omni-directional acoustic tracking coverage, so is ideal for tracking targets in shallow water all the way to the surface.

Micro-Ranger 2 software comes with a lot of advanced and powerful features selected from our Mini-Ranger 2 and Ranger 2 USBL systems to ensure you have everything you need to track underwater targets. If you need to track and also communicate with small AUVs and drones, an optional marine robotics feature pack is available.

Nano is a popular choice for use with Micro-Ranger 2 when tracking divers, man-portable AUVs and micro ROVs.
