An increasingly important area of work for us is unmanned aircraft systems. The systems we work on help prevent aircraft accidents and ensure safe organization of air traffic. With technical expertise in real-time software architecture, radio-frequency and digital hardware design, advanced supercomputing-enabled modeling and simulation, machine learning, and system integration, our research teams take new ideas for solving problems and develop them into working prototypes. We are currently working on detect and avoid systems for both unmanned aircraft systems and new surveillance systems for smaller airports. We are also developing analytical methods to help automated vehicles integrate safely and efficiently into the current surface transportation system.
