Research Interests

Navigation and Control, applied to aircraft, spacecraft and automobiles. He is the author of over 100 papers and two texts on Control Systems. Professor Powell's research is concerned with GPS based aircraft and ground vehicle navigation. His research involves the use of GPS for aircraft surveillance and collision avoidance, the use of GPS-based attitude with low cost inertial instruments for an aircraft attitude reference, and the use of GPS-enabled pilot displays for enhanced traffic displays along with their wake vortices.
