In the mid-1990s, there were two global satellite-based navigation systems, the United State's Navstar Global Positioning System (GPS) and the Russian Federation's GLObal NAvigation Satellite System (GLONASS). While the GLONASS constellation and quality of service deteriorated in the late 1990s, GPS has become the world standard and has revolutionized the world's positioning, navigation, and timing. Millions of receivers worldwide and a virtually endless number of applications testify to the reliable and high quality positioning and time provided by GPS. Now, more satellite-based navigation systems are being developed by other nations, while GPS and GLONASS are each being modernized. The result will be more systems, more satellites, and more signals, along with improved signal designs that offer receiver designers the opportunity to provide even better performance than is obtained from GPS today. This presentation reviews the history and looks at the future of satellite-based navigation. It discusses some of the challenges associated with the growing number of systems, and relates strategies being employed to deal with these challenges.
Speaker's Bio:
Dr. John W. Betz is a Fellow of The MITRE Corporation. Since 1997 he has worked on satellite-based navigation involving the Navstar Global Positioning System (GPS) and also, since 2002, on international negotiations concerning compatibility and interoperability of GPS with other satellite-based navigation systems including Europe's Galileo system, Japan's QZSS, Russia's GLONASS, India's IRNSS, and China's COMPASS. Since 2004, he has been a member of the U.S. Air Force Scientific Advisory Board. He was named Chair of this Board in October 2008, leading 52 engineers and scientists selected from academia and industry who serve as a major force in determining U.S. Air Force research and development policy and provide technical advice to Air Force senior leadership. He holds a PhD in Electrical and Computer Engineering from Northeastern University, and has been a lecturer and Adjunct Professor at Northeastern. He has authored or coauthored more than 50 refereed journal papers, book chapters, and papers in conference proceedings, and holds two patents. Dr. Betz is a 2009 Fellow of the IEEE, and also a Fellow of the Institute of Navigation. For his role in the United States/European Union negotiations on GPS and Galileo, he received the U.S. State Department Superior Honor Award.
