Micro-Ranger 2 USBL- Underwater Target Tracking

Tracks every move of your divers and underwater robots as they explore rivers, lakes, reservoirs, harbours and coastal water
Never used a USBL system before? No problem. Micro-Ranger 2 is simple to setup and use
Deploy it from a dockside, RIB or even from unmanned surface vessel; no special hardware needed
Up to 995 m range; no need for an export license to transport internationally

Need to know where your targets are? Micro-Ranger 2 has them covered.

It maybe our smallest ever underwater tracking system, but Micro-Ranger 2 will have a big impact upon your Search and Rescue, inspection and survey operations. Precision, ease of use and versatility come as standard – and its small enough to use with divers and the smallest ROVs

Portable and quick to mobilise, Micro-Ranger 2 can be used from any waterside location or vessel, including RHIBs and small survey vessels, to track divers, remote and autonomous underwater vehicles and equipment. It’s built around the same market-leading 6G hardware and Wideband 2 digital acoustic technology you’ll find in our family of deep water USBL systems, Mini-Ranger 2 and Ranger 2, but for significantly less cost and complexity.

Everything needed to start tracking divers, remotely operated vehicles, autonomous underwater vehicles or any other subsea targets is contained in a single, IP67-rated ruggedised case small enough to operate-anywhere, from anything.

The one-box USBL solution is able to track up to 10 targets out to 995 m meaning export-free ownership. Inside the case is a Micro-Ranger Transceiver (MRT) with 10 m of cable, a GNSS antenna with 5 m of cable, and two Nano transponders and command hub. A built-in battery provides more than 10 hours of continuous use, enough for a full day of activity out on the water. The case can also accept external power from your boat or shore supply.

To get started, you simply have to connect your laptop running Ranger 2 software to the case via Wi-Fi, put the MRT in the water, connect the antenna, and fit a Nano to each target. First-time operators can expect to be up and running in around 30 minutes.

Nano transponders are the perfect size and weight for divers, small towfish and micro ROVs. The two that come in the case are our second-generation model, offering extended battery life and depth rating. A connector-equipped Nano is also available allowing it to operate continuously via an external power source. Choose the type of Nano transponder required at time of ordering.

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 Integrator Kit is available. This kit replaces the Nanos with an AvTrak 6 Nano. It is also provided with an integration guide to ensure that integrating our acoustics into your AUV operations is seamless.

Technical Bulletins

Title Description
Important Security Features of the Marksman/Ranger2 Navigation Computer – No 11-003 The latest Windows XP Image (8026-051-A/B) on the Marksman / Ranger2 Navigation Computer has additional security features to minimise the risk of virus infections and system tampering. These include pre-installed antivirus software and a dual login feature. Note that this does not affect the NavPCs used for any other software products.
Marksman/Ranger 2 V3.01 CASIUS Processing Error – TB12-001 Marksman/Ranger 2 pitch/roll/heading measurements imported into CASIUS have an offset. When a .CAS file is saved by CASIUS, the resulting file contains the wrong pitch/roll/heading measurements. A fixed angular offset is added to the transceiver pitch/roll/heading corrections, leading to a shift in beacon positions, depending on water depth. A spin test would reveal the offset.
