George T. Schmidt is a member of the Board of Governors of the IEEE Aerospace and Electronic Systems Society (AESS) and an avionics consultant. He has served on NATO’s Research and Technology Organization (formerly AGARD) since 1968 and was the director of several NATO-RTO Lecture Series related to navigation in GPS denied environments. In 2005 he received NATO’s highest technical award, the von Kármán medal. For 17 years he served as Editor-in-Chief of the AIAA Journal of Guidance, Control, and Dynamics which experienced unprecedented growth during his tenure. He managed the peer review of more than 6500 submitted papers. The AIAA awarded him the International Cooperation Award in 2001. During his 46 years at MIT and Draper Laboratory, he held positions that included Leader of the Guidance and Navigation Division, Director of the Draper Guidance Technology Center, Education Director, and Lecturer in Aeronautics and Astronautics. He is an AIAA Fellow and an IEEE Life Fellow. He is the author of more than 100 technical publications. He received his SB, SM and ScD degrees from MIT.
Prof George highlighted use of Position, velocity, and timing (PVT) signals from Global Navigation Satellite Systems (GNSS) throughout the world. However, the availability, reliability, and integrity of these signals in all environments have become a cause for concern for both civilian and military applications. International news reports about a successful GPS spoofing attack on ships navigating the Black Sea in June 2017 have caused concerns. Prior to that, reports about a successful GPS spoofing attack on a civilian UAV in the USA increased questions over the planned use of UAVs in the national airspace and the safety of flight in general. Jamming of GPS by the North Koreans has interfered with ship and aircraft navigation for several years. Recently, the Russians have apparently equipped cell towers with GPS jamming devices as a defense against attack. All of these incidents have led the navigation community to search for reliable solutions in the face of spoofing and jamming. Based on his own experiences with navigation systems since Sputnik and Apollo, the presenter gave an historical and personal perspective on what is required for civilian and military navigation applications now and in the future.
