Expert Advice: EPIC Happening — Europe’s PNT Industry Council

September 1, 2011 - By

We have the United States GPS Industry Council, the Japan GPS Council, and the Korean GNSS Technology Council. Anything missing? The challenges facing the performance, navigation, and timing (PNT) community, which relies on GNSS amongst other things, are getting more numerous and complex, and Europe is the only major territory without a unified industry nexus where such challenges can be engaged. However, this is about to change. read more

Out in Front: The Good, the Bad, the Incompetent

September 1, 2011 - By

The most efficient use of spectrum the world has ever seen benefits more than a billion people today. Two billion tomorrow, when modernized and interoperable GNSS gets real. This massive installed base constitutes a source of innovative advantage and invaluable good will for the United States. The latter arises from the high degree of trust and confidence in the United States and its stewardship of GPS, one of the most successful — and perhaps only — simultaneous foreign aid and domestic economic stimulus programs ever created. read more

The System: 2 SOPS Takes Over Second IIF

September 1, 2011 - By

The U.S. Air Force 50th Space Wing’s 2nd Space Operations Squadron took command and control of the second GPS Block IIF satellite on August 19. SVN-63 (PRN 01) was set healthy on August 23. The total of 12 next-generation GPS IIF satellites built by Boeing will provide improved accuracy through advanced atomic clocks, a longer design life than legacy GPS satellites, and a new signal, L5, that will benefit civil aviation and safety-of-life applications. The Space and Missile Systems Center’s GPS Directorate at Los Angeles Air Force Base remained in control of the satellite during a 30-day on-orbit check-out period before hand off. read more

Expert Advice: Exploring the Technologies Behind Location-Gate

September 1, 2011 - By

For the past several months, controversy has raged over the revelation that Apple and Google tracked mobile subscriber location movements and stored that information in an unencrypted file on the handset, where it was potentially vulnerable to hacking and other inappropriate usage. The resulting Location-gate scandal highlights the sometimes tenuous control of mobile subscriber information versus the business objectives of dominant platform and applications providers. These business objectives may include immediate revenue opportunities from the subscriber being tracked or broader self-interest initiatives, such as collecting marketing data that may be valuable to third parties like advertisers, or building subscriber-reported Wi-Fi access point databases. read more

Locata, A New Constellation: ICD and Live Demos at ION-GNSS 2011

September 1, 2011 - By

"A large number of companies and engineers have thrown billions of dollars at trying to improve GPS in urban and indoor applications,” states Locata Corporation co-founder Nunzio Gambale. “From a technological perspective, Locata has created something completely new: the capability to autonomously create a GPS-style system on the ground.” Members of the GNSS community can see for themselves at Locata’s coming-out party at ION-GNSS 2011, including release of a Locata signal interface control document (ICD). GPS World took an advance look at the technology in a June trial of the demo that all ION attendees can see. This article presents these reports. read more
