Spatial Integrated Systems Inc. (SIS) has won a proof-of-concept contract from DARPA in response to its recent solicitation for the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) program. The award builds on SIS's successful development of an autonomous maritime navigation and control system in partnership with NASA Jet Propulsion Laboratory (NASA JPL) and Naval Surface Warfare Center, Carderock Division. Under the initial six-month contract, SIS will demonstrate the technical feasibility of a beyond-state-of-the-art cognitive capability for tracking diesel-electric submarines for long periods of time under sparse remote supervisory control. The results of this demonstration will be used to generate preliminary performance specifications for the ACTUV's autonomy system. SIS's AMN system provides a platform-independent executive function that can be used with any USV. At the heart of AMN's cognitive capabilities is an artificial intelligence engine originally developed by NASA JPL for the Mars Exploration Rovers.
