GPS Not Off the Hook at U.S. Department of Transportation’s Distracted Driving Summit

News 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.

Good, But Not Great

This 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).

Easy Access

As 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.

Fireside GPS

My 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.

OCX budget Cut Could Slow Program; First IIF Might Launch by May 2010

An 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.

EC to Declare EGNOS Operational for Non-Safety-of-Life Use

The 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).
