Potential NASA Commercial Applications: NAS Integration and Air Traffic Control (NASA NextGen Program): For the past decade, NASA has been working to develop NextGen Air Traffic Control (ATC) Management capabilities that will provide increased efficiency and throughput of the National Air Space (NAS) to meet growing system demands. The SOMAV STK module for multiple-UAS command and control directly promotes these efforts in several ways. First, it provides a high-fidelity simulation environment for testing potential ATC routing algorithms, particularly those for systems of UAS platforms. Second, our tool reduces human operator workload by pushing much of the low-level control onto the UAV platforms themselves and having the routing/coordination performed autonomously. Reducing operator burden is listed as a specific goal of within Topic A2.02 Unmanned Aircraft Systems Technology of this SBIR effort. Third, our UAS routing and coordination tool will automatically optimize separation assurance for the UAS platforms in each team, which relates to the goal of safely and seamlessly integrating UAS platforms into NextGen. Fourth, the proposed module directly promotes autonomous operation for systems of UAS platforms using machine intelligence for decision-making. Finally, the UAS coordination tool addresses NASA's goal of advancing the state-of-the-art in autonomous navigation under uncertain conditions (e.g., collision/hazard avoidance) and cooperative task completion.
