John Betz

John BetzDr. Betz is a Fellow of the MITRE Corporation, involved in programs that develop and apply advanced technologies in communications, surveillance, and navigation. Since 1997, he has worked primarily on signals, receiver processing, and systems engineering for the Global Positioning System (GPS) and other satellite-based navigation and timing systems.

Dr. Betz was a member of the U.S. Air Force Scientific Advisory Board (SAB) from 2004 to 2012, serving as its chairman from 2008 to 2011, leading 52 accomplished engineers and scientists who advise the Air Force senior leadership.

Dr. Betz led the team of scientists and engineers designing the modulation and acquisition of the M-code signal, the modernized GPS military signal. He developed the binary offset carrier (BOC) spreading modulation, and models for predicting its performance. He also contributed to the design of the GPS L1C civil signal, and was integral to the design of the Multiplexed BOC (MBOC) concept and the time-multiplexed BOC (TMBOC) spreading modulation used for L1C.

Dr. Betz was a lead technical contributor to the U.S. delegation in negotiations with the European Community concerning GPS and Galileo, leading to the 2004 Agreement between the U.S. and European Community. He also has been a key member of technical working groups between the U.S. and Europe, Japan, the Russian Federation, China, and India, leading to other nations' adoption of civil signals compatible and interoperable with GPS. His recent work focuses on making navigation and timing more robust and resilient for military and critical infrastructure applications.

From 1994 to 2000, Dr. Betz was an Adjunct Professor of Electrical and Computer Engineering at Northeastern University and from 2005 to the present he has been an instructor for NavtechGPS, teaching short courses in North America and Europe on topics related to satellite-based navigation and timing systems, signals, and receiver processing.

Dr. Betz received a B.S. in Electrical Engineering from the University of Rochester in 1976, and a M.S. (1979) and Ph.D. (1984), both in Electrical Engineering from Northeastern University. He is co-inventor on four patents or patent applications, and authored Engineering Satellite-Based Navigation and Timing: Global Navigation Satellite Systems, Signals, and Receivers (Wiley-IEEE Press, 2015), along with more than 50 other publications including book chapters, journal articles, and conference papers. He has received numerous national and international awards.
