Instructors:

Christopher Hegarty, D.Sc., is a director with The MITRE Corporation, where he has worked mainly on aviation applications of GNSS since 1992. He is currently the chair of the Program Management Committee of RTCA, Inc., and co-chairs RTCA Special Committee 159 (GNSS). He served as editor of NAVIGATION: The Journal of the Institute of Navigation from 1997 – 2006 and as president of the Institute of Navigation in 2008. He was a recipient of the ION Early Achievement Award in 1998, the U.S. Department of State Superior Honor Award in 2005, the ION Kepler Award in 2005, and the Worcester Polytechnic Institute Hobart Newell Award in 2006. He is a fellow of the ION, a 2010 fellow of the IEEE, co-editor/co-author of the textbook Understanding GPS: Principles and Applications, 2nd edition and is NavtechGPS’ modernization technical advisor.

Michael S. Braasch, Ph.D.,is a Thomas Professor of Electrical Engineering and has served as the director of the Avionics Engineering Center at Ohio University. His research includes GPS receiver design, GPS/INS integration, multipath mitigation, advanced cockpit displays and UAV operational safety analysis. Dr. Braasch has served as a technical advisor both to the FAA and the International Civil Aviation Organization (ICAO) in the area of precision approach and landing systems, and he has received international recognition for his work on characterizing the effects of multipath on GPS/GNSS accuracy. As co-founder of the company GPSoft, Dr. Braasch has been instrumental in the development the Satellite Navigation (SatNav) Toolbox, the Inertial Navigation System (INS) Toolbox, and the Navigation System Integration & Kalman Filter Toolbox for MATLAB. Dr. Braasch is a fellow of the Institute of Navigation, a senior member of the IEEE, is an instrument-rated commercial pilot and is a licensed professional engineer in the State of Ohio.
