LPA and AutoNaut Sea Trials Show Success
J+S Limited’s first deployment of its miniaturised low profile acoustic array (LPA) off Plymouth Sound proved a resounding success. J+S were very pleased with the performance of the array when towed by AutoNaut® a newly developed UK unmanned surface vessel (USV).
Ease of handling and the robust nature of the array was clearly demonstrated. The array was able to track a target of opportunity and with the absence of tow vessel noise, 360 degree coverage was achieved.
The trial was part of the NOC and DSTL funded Phase 2 Long Endurance Marine Unmanned Surface Vessel (LEMUSV) project.
In a chilly 15 knot wind and small chop, the wave-propelled AutoNaut® by MOST (Autonomous Vessels) Ltd deployed and towed the 18 metre acoustic array with ease. Mike Poole, Director of MOST (AV) commented: “The vessel’s speed of around two knots was not noticeably changed and her steering remained good with a series of circles being completed without difficulty. It was great to see the J+S array in action with our new boat. Our collaboration with J+S Ltd is a triumph of innovative UK engineering expertise at its best”
Andy Toms, Managing Director for J+S said: “This successful trial is the result of months of intensive sonar engineering work by our Product Development Team. The collaboration with MOST (AV) demonstrates the potential of our LPA technology as a lightweight, easily deployed, acoustic sensing system”
