Sonardyne Mini-Ranger 2

With a 995 m operating range, extendable to 4,000 m, Mini-Ranger 2 can track up to 10 underwater targets simultaneously, including divers, towed instruments, ROVs and AUVs. An optional Marine Robotics software pack enables communication with targets – enabling for example, data harvesting from seafloor instrument packages using an uncrewed surface vessel (USV).

Mini-Ranger 2 is a compact, easy-to-install and use system, so it’s the ideal choice for temporary deployment on small survey vessels, as well as uncrewed surface vessels (USVs). It’s built around the same market-leading 6G hardware and Wideband 2 digital acoustic technology you’ll find in our entire family of USBL systems – even the software is the same.

• Performance without the cost and complexity of a deep water USBL solution
• Perfect for nearshore operations; UXO surveys, search and recovery, structure inspection
• Portable and quick to mobilise; a great choice for small survey vessels, moored barges and uncrewed vessels
• 995 m operating range; extendable to 4,000 m (requires export license)
• Optional Marine Robotics software feature pack provides command and control of AUVs
• Works with a wide range of 6G transponders including RT 6 acoustic releases

HPT 3000

At the heart of the system is HPT 3000, a highly capable surface-deployed USBL transceiver optimised for performance in shallow water, high elevation and long lay back operating scenarios, as well data telemetry. HPT 3000 is connected to the system’s 1U-high Ethernet Serial Hub (ESH) and your PC running the Ranger 2 software application. Fit a transponder to each target you want to track and you’re ready to get your operation underway.

Transponder options

A wide range of Sonardyne 6G transponders can be used with Mini-Ranger 2, allowing you to select the most appropriate model for each task. If you’re tracking divers, man-portable AUVs and micro-class ROVs, Nano is a popular choice. When tracking larger targets such as a towfish, a crane wire lowering a structure, or an observation-class ROV, WSM 6+ will meet your requirements. And if you’re looking for a combined tracking and acoustic release transponder, RT 6 is now available. It allows you to deploy, track and recover seafloor equipment, all using the same instrument.

The Sonardyne Mini-Ranger 2 is used for diverse applications including:

• Environmental surveys
• Autonomous Underwater Vehicles
• Aquaculture
• Coastal science
• Sensor tracking
• Research vessels
• Site survey and characterisation
• Naval test ranges
• Military diving
• Uncrewed Surface Vehicles
• Remotely Operated Vehicles
• Tracking and communications
