GPS Not Off the Hook at U.S. Department of Transportation’s Distracted Driving SummitNews reports about the U.S. Department of Transportation (DoT) Distracted Driving Summit now underway in Washington, D.C., (September 30–October 1) have focused on the role of mobile phones in vehicle accidents. According to transportation officials, driver distraction was involved in 16 percent of all fatal crashes during 2008. People • September 29, 2009
Aerospace Engineer Penina Axelrad Receives ION Kepler AwardPenina "Penny" Axelrad, University of Clorado professor of aerospace engineering sciences, has received the Johannes Kepler Lifetime Achievement Award from the Institute of Navigation (ION) Satellite Division. The institute made the award on the final day (September 25) of its ION GNSS 2009 conference held in Savannah, Georgia. Inside GNSS • September/October 2009
Good, But Not GreatThis book is a welcome addition to the GNSS textbook literature by the team of authors who have since 1992 produced five editions of an excellent book on GPS targeting high precision users, Global Positioning System (GPS): Theory and Practice. Hofmann-Wellenhof is also the lead author of the 2003 book, Navigation, and for the second edition of the classic Physical Geodesy (2006). Inside GNSS • September/October 2009
Easy AccessAs an engineer, I always believed that the only clear way to communicate a theory or technique must involve the use of mathematics or data plots. Ahmed El-Rabbany’s book is the proof that this is not necessarily so. Introduction to GPS: The Global Positioning System, now in its second edition, is clear and concise in its description of all the principles and main techniques behind GPS, supported only by simple examples and figures. The formulas are so elementary (and rare) that they are embedded naturally in the text. Inside GNSS • September/October 2009
Fireside GPSMy history with GPS began during the time of the “Cold War” in what was then Czechoslovakia. In 1975, the ION Journal of Navigation was the only information available to me. Despite that, my team at the Czech Technical University developed a GPS receiver and measured the position of our faculty in 1984. In those relatively isolated years, we gained a good deal of experience with GPS signals. September 17, 2009
OCX budget Cut Could Slow Program; First IIF Might Launch by May 2010An increasingly likely $97.4-million cut in the GPS OCX budget for fiscal year 2010 (FY10) would slow down work on modernization of the operational control segment, but the Air Force would try to recoup any reduction in the FY11 budget. Meanwhile, technical problems that have delayed development of the follow-on generation of Block IIF satellites are largely resolved and a first launch is expected in May 2010.

GPS Wing, Lockheed Martin, 2nd SOPS Panelists to Discuss SVN49 at ION GNSS 2009Col. David Goldstein, the GPS Wing’s chief engineer, will chair a panel discussion on SVN49’s current status, issues and options for moving forward at the Institute of Navigation’s ION GNSS 2009 conference in Savannah, Georgia on Wednesday, September 23. Goldstein will be joined by Col. David Madden, GPS Wing commander and representatives from Lockheed Martin, navigation payload contractor; the 2nd Space Operations Squadron at Schriever Air Force Base that fly the GPS satellites; and members of the civil GPS community.

EC to Declare EGNOS Operational for Non-Safety-of-Life UseThe European Commission (EC) expects to declare in October that the European Geostationary Navigation Overlay Service (EGNOS) — which provides satellite-based augmentation signals for GPS and Galileo — is operationally ready as an open and free service for non-safety-of-life (non-SoL) applications, according to a press release from the GNSS Supervisory Authority (GSA).
