By Inside GNSS Jules G. McNeff has a deep and lengthy background in GPS program operation and policy from within the U.S. defense community. He began a 20-year career in Air Force space systems in 1972.
He served for several years in the Office of the Assistant Secretary of Defense and was responsible for Defense Department navigation systems policy and overall management and oversight of the GPS program.
By Inside GNSS John W. Betz developed the binary offset carrier modulation and participated in the design of modernized signals including GPS M code and L1C. He contributed to aspects of receiver processing for modernized signals and a range of systems engineering activities in support of GPS modernization.
He has participated in bilateral discussions between the United States and the European Community, Japan, Russia, and other nations, and helped improve compatibility and interoperability of current and future GNSSs.
By Inside GNSS Changdon Kee is a professor and associate head of the School of Mechanical and Aerospace Engineering at Seoul National University. He developed the basic concept and presented the first experimental test results of wide area differential GPS in the early 1990s.
Kee has published widely on GNSS, pseudolites, space mechanics and UAV Automatic navigation and control and holds more than 15 domestic and international patents for his work on GNSS.
By Inside GNSS Jean-Luc Issler heads the Transmission Techniques and Signal Processing Department of CNES, the French space agency. His department’s main tasks are signal processing; air interfaces and equipment in radionavigation; tracking, telemetry, and control; propagation; and spectrum survey.
He has been involved in the development of several spaceborne receivers in Europe, as well as in studies on the European radionavigation projects, such as GALILEO and pseudolite networks.
By Inside GNSS Per Enge is the Kleiner-Perkins, Mayfield, Sequoia Capital Professor in the School of Engineering at Stanford University. He is coauthor, with Pratap Misra, of the textbook, Global Positioning System: Signals, Measurements, and Performance.
By Inside GNSS Professor Vidal Ashkenazi is chief executive of U.K.-based Nottingham Scientific Ltd, and a Fellow of the Royal Academy of Engineering. He was the founding director of one of the leading space geodesy research institutes in Europe and has supervised about 50 doctoral (Ph.D.) students, many of whom now occupy senior positions in universities and industry in several countries.
By Inside GNSS Professor František Vejražka graduated with a master of science degree in engineering from the Faculty of Electrical Engineering of the Czech Technical University in Prague, Czech Republic and gained the CSc. (PhD.) degree in 1972. He has been a full professor of radio navigation, radio communications and signals and systems theory since 1996.
By Inside GNSS In 2007, Linyuan Xia was appointed as a leading professor at Sun Yat-Sen University in Guangzhou, China, where he conducts research and teaches on satellite positioning and surveying.
For the previous 11 years, Xia served as an associate professor at the State Key Laboratory for Information Engineering on Surveying, Mapping and Remote Sensing (LIESMARS), Wuhan University, Wuhan, China. He has a broad and diverse experience in satellite navigation research and applications.
By Inside GNSS Akio Yasuda is chairman of the GPS Society of the Japan Institute of Navigation and vice president of the Japan GPS Council. From 1986 to 2003 he was a professor at Tokyo University of Mercantile Marine. Since 2003, he has been a professor in the faculty of Marine Technology, Department of Maritime System Engineering, at the Tokyo University of Marine Science and Technology, where now holds emeritus status.
By Inside GNSS Dr. Misra is a research associate professor at the Tufts University School of Engineering in Medford, Massachusetts, USA. He is also a senior principal engineer at The MITRE Corporation in nearby Bedford.
Since 1989, his professional focus has been on global navigation satellite systems and their use in civil aviation.
