2016 Fellow

Presented to: Dr. Gary McGraw

Citation: For sustained contributions to the development of highaccuracy and high-integrity Positioning, Navigation, and Timing technologies for a variety of military and civil aviation applications.


Dr. McGraw has made groundbreaking contributions in the areas of GPS receiver technology, integrity monitoring, high accuracy GPS processing, and civil and military GPS modernization. He led the Rockwell Collins relative navigation development efforts on the Joint Precision Approach and Landing System (JPALS) program that pioneered the use of high anti-jam GPS receivers for high accuracy/ integrity applications. He was instrumental in the development of precision truth reference system algorithms for DOD test range applications, which demonstrated the application of highaccuracy Precise Point Positioning techniques on high-dynamic aerial platforms. He led the development of the GPS Receiver Autonomous Integrity Monitoring algorithms in Rockwell Collins’s commercial GPS products, which are used by airlines worldwide. He has also been instrumental in the development of high-accuracy PNT capabilities using tactical data links for a variety of GPS-denied applications.

Dr. McGraw supported the work of RTCA SC-159, notably in the areas of LAAS standards developments and GPS/WAAS link budget and interference issues, and definition of the GPS L5 signal. He has also made important contributions in GPS signal processing for multipath mitigation and optimal carrier smoothed code processing.

Dr. McGraw is a Technical Fellow and manager of the Navigation and Control section of the Advanced Technology Center at Rockwell Collins. Previously, he was employed at the Aerospace Corporation, Hughes Aircraft Company, and Sperry Flight Systems. He received his M.S. and Ph.D. in Electrical Engineering from University of California Los Angeles and B.S. in Electrical Engineering and Mathematics from Iowa State University. He has published extensively, serves as an associate editor of the ION journal, NAVIGATION, and has held numerous volunteer positions within the ION. He is a past recipient of the ION Satellite Division’s Kepler Award (2011) for sustained and significant contributions to the field of satellite navigation.
