What Do Your Colleagues Think? Part 2

November 28, 2010 - By

In my last column, I presented the poll results from my November 16 webinar "A Buyer's Guide to GPS/GIS Mapping Equipment." I've conducted many webinars over the years, and the audiences have been comprised of hundreds (if not thousands) of participants who have the ability to ask questions and also participate on various polls I conduct during the webinars. This column continues the look back at previous polls conducted during my various webinars. read more

What Do Your Colleagues Think?

November 23, 2010 - By

Over the past several years, I've conducted many webinars on different GPS/GNSS and other geospatial technologies. The audiences have been comprised of hundreds (if not thousands) of participants who have the ability to ask questions and also participate on various polls I conduct during the webinars.The poll results are a powerful tool that illustrates what your colleagues think about GPS/GNSS, their field practices and general attitude about geospatial technology. read more

Galileo from the Top: Interview with the EC’s Paul Verhoef

November 20, 2010 - By

Paul Verhoef, the European Commission’s program manager for European Union (EU) satellite navigation programs — namely Galileo — discussed current issues at some length with GPS World, in a conversation on November 10. He addressed aspects of interoperability with GPS and prospects for further development in that area, the need for an ongoing political commitment by the EU to Galileo, the challenges of financing, the prospects for an 18-satellite constellation (which he dismisses as unrealistic), military considerations for both Galileo and GPS, and the recent uncertainty around Galileo’s Public Regulated Service. read more

J911: Fast Jammer Detection and Location Using Cell-Phone Crowd-Sourcings

November 1, 2010 - By

Inexpensive, readily available GPS jammers constitute a threat to safety, national infrastructure, and industry revenue streams. Cell phones could incorporate GPS jam-to-noise (J/N) ratio detectors to provide timely interference detection and effective localization, with a flexible and updateable system since the crowd processing function resides in software. read more

Out in Front: An Open or Shut Case

November 1, 2010 - By

Engineers are an eager lot, by and large. They like talking about their work, openly showing information and results, testing their work against data and alternate hypotheses, getting feedback and even critique from colleagues near and far. They value an iterative, elaborative, collaborative process. Politicians and business managers, on the other hand, tend to the dour. They would rather not show their hand, nor do they care to hear what you think of their organization’s work, citing intellectual property or national security reasons. read more

Expert Advice: Block IIR Lifetimes and GPS Sustainment

November 1, 2010 - By

In 2009, a Government Accountability Office (GAO) report claimed that the GPS constellation was extremely vulnerable to failure, and a recent September 2010 GAO follow-up continues to make that assertion. In this article, we present the technical data to contradict some of the GAO report conclusions. read more

Where Time and Space Meet

November 1, 2010 - By

Increasing availability and performance of state-of-the-art navigation sensors motivates the need for a highly accurate reference system commonly referred to as a time-space position information (TSPI) device. The Advanced Navigation Center at the Air Force Institute of Technology is working with the Air Force Flight Test Center to develop a next generation time-space position information (TSPI) system to be used for test and evaluation of modern navigation devices. read more
