Introducing your next-generation Gyro USBL transceiver. Smaller, lighter, and packed with advanced features, it’s the ultimate solution for your precise subsea tracking operations. It works seamlessly with Ranger 2 to track the position of a subsea target from a USV, vessel of opportunity or from a pipelay vessel’s stinger over extreme ranges. Gyro USBL delivers the highest precision available and is now pre-calibrated direct from us, saving you precious operational time.
Key benefits
Saves you time and money: pre-calibrated for immediate deployment, eliminating setup delays.
Enhanced accuracy: delivers unparalleled precision through a combined acoustic transceiver and AHRS.
Versatility: ideal for a variety of applications, including subsea structure installation, pipeline positioning and USV operations.
Compact design: up to 20% shorter and 19 kg lighter than previous versions. It’s perfect for use in space-constrained environments such as on over-the-side poles and pipelay vessel stingers.
Optimised performance: seamless integration with Ranger 2 for superior tracking accuracy.
Gyro USBL is more than just a tool – it's a game-changer. Whether you're in energy, defence, or science, our advanced technology will elevate your operations with:
How it works
Combining our cutting-edge 6G acoustic transceiver with a high-performance AHRS, Gyro USBL eliminates the lever arm offsets, pole bending and ship flexing errors common in traditional USBL systems. Its compact, corrosion-resistant design ensures durability in any marine environment.
