Leidos’ autonomy system completes voyage

29th January 2015 - 13:18 GMT | by Shephard News Team

RSS

Leidos’ prototype autonomous maritime system for the DARPA Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) programme recently completed its first self-guided voyage between Gulfport and Pascagoula, Mississippi, the company announced on 26 January.

The prototype system was installed on a 42-foot work boat that served as a surrogate vessel to test sensor, manoeuvring, and mission functions of the prototype ACTUV vessel. ACTUV seeks to develop an independently deployed, unmanned naval vessel that would operate under sparse remote supervisory control and safely follow the collision avoidance ‘rules of the sea’.

Controlled only by the autonomy system, and with only a navigational chart of the area loaded into its memory and inputs from its commercial-off-the-shelf (COTS) radars, the surrogate vessel successfully sailed the complicated inshore environment of the Gulf Intracoastal Waterway. During its voyage of 35 nautical miles, the maritime autonomy system functioned as designed. The boat avoided all obstacles, buoys, land, shoal water, and other vessels in the area – all without any pre-planned waypoints or human intervention.

While Leidos continues to use the surrogate vessel to test ACTUV software and sensors, the company is continuing construction of Sea Hunter, the first ACTUV prototype vessel, in Clackamas, Oregon. Sea Hunter is scheduled to launch in late fall 2015 and begin testing in the Columbia River shortly thereafter.
