Michael Braasch holds the Thomas Professorship in the Ohio University School of Electrical Engineering and Computer Science and is a Principal Investigator with the Ohio University Avionics Engineering Center (AEC). He received his B.S.E.E. in 1988, M.S.E.E. in 1989 and Ph.D. in 1992, all from the Ohio University. He has been involved in aviation navigation system research with the AEC since 1985 and has worked on a wide variety of navigation systems including DME, GPS, ILS, INS, Loran-C, MLS, VOR, integrated navigation systems (e.g., GPS/INS), cockpit displays and UAV technologies. He has served as a technical advisor both to the U.S. FAA and the International Civil Aviation Organization (ICAO).
Mike has served as a member of the EE faculty at Ohio University since 1994 and has developed and taught graduate courses in GNSS, inertial navigation, Kalman filtering and navigation system integration. Mike is internationally recognized for his work in characterizing the effects of multipath (e.g., unwanted signal reflections) in GPS. His research has included the analysis of multipath measurement/isolation techniques, proof of the existence of long-delay multipath error in pseudorandom noise code ranging systems, characterization of the influence of the code-tracking loop on carrier-phase multipath error and characterization of the influence of phase rate-of-change on multipath error. In addition, Mike’s research in the application of phased-array techniques to differential GPS ground reference stations laid the foundation for the development of the first generation prototype antennas for the FAA’s Local Area Augmentation System (LAAS).
Following the launch of the first operational GPS satellite in 1989, Mike developed and published the first model of the intentional signal degradation known as Selective Availability. In the mid 1990s, Mike led the Ohio University research group that pioneered the GPS software-defined receiver. He has also conducted research in the design, development and flight-testing of peripheral vision display systems for general aviation aircraft (shown to reduce the likelihood of spatial disorientation during instrument meteorological conditions). Mike also has extensive flight-testing experience with Ohio University’s fleet of research aircraft (e.g., PA-32 Piper Saratoga, Douglas DC-3, AeroVodochody L-29 Delfin).
Mike has served as a visiting scientist at the Delft University of Technology in The Netherlands and has lectured for NATO AGARD in Russia, Turkey and Ukraine. He has authored book chapters in the area of GPS in addition to numerous conference papers and journal articles. He is a Senior Member of the IEEE, a Fellow of the U.S. Institute of Navigation, a licensed professional engineer in the State of Ohio and is an instrument-rated commercial pilot. From 2006 – 2009, Mike served as an associate editor for navigation for the TAES and served as the technical editor for navigation for the TAES from 2010 – 2011. Since 2014 he has served as the IEEE/AESS liaison to the ION/IEEE Position, Location and Navigation Symposium (PLANS). Since 2015, he has served as the associate editor for navigation for the AES Systems Magazine.
