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

September 1, 2011

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.

Expert Advice: Exploring the Technologies Behind Location-Gate

September 1, 2011

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.

Expert Advice: Cloud-Based Location Changes Enterprise Playing Field

September 1, 2011

New technology and wireless carrier openness now make real-time access to telephone location information available to the enterprise with no application required on the mobile device. Yes, that’s right: no application required! Cloud-based location, offered via direct connections to wireless operators, changes the playing field for enterprises to introduce instant operational efficiencies. Marrying location insight, privacy controls, and multi-modal communications through network application programming interfaces (APIs) provides enterprises with flexibility, cost savings, and time-to-market advantages. Whether delivering geo-targeted promotions, dispatching services, verifying worker activities, or performing other location-relevant actions, businesses now have cross-carrier access to location information for more than 85 percent of U.S. wireless subscribers — instantly!

Expert Advice: Who Won?

August 1, 2011

Thousands of man hours and millions of dollars later, we finally have the 975-page GPS Technical Working Group (TWG) report, confirming what five minutes of back-of-the-envelope calculation predicted. Hooray for our side, good job GPS Industry Council; we’ve won the war and the foe is vanquished, never to brighten our skies again. Well, maybe. LightSquared is now bypassing the Federal Communications Commission (FCC) and submitting technical papers directly to the United Nation’s International Telecommunications Union (ITU) Working Party that handles mobile satellite services (MSS) and radio determination satellite service (RDSS spectrum) and orbits (ITU-R WP 4C).

Expert Advice: Critical Offshore Applications of SBAS GNSS

July 1, 2011

Precise positioning of many different kinds of vessels and other equipment depend upon satellite-based augmentation systems (SBAS) of GNSS, principally GPS and GLONASS at this time. The applications range from exploration to production and delivery of hydrocarbons to shore-based installations and navigation of very large crude carriers, or oil tankers. Decisions and recommendations are strongly needed to keep these services free from interference.

Dear Chairman Genachowski: The National Ocean Industries Association (NOIA), which represents approximately 270 member companies involved in outer continental shelf (OCS) energy production throughout the United States, is gravely concerned over the pending allocation of Mobile Satellite Services (MSS) spectrum to LightSquared, Inc. for terrestrial high-powered transmissions. LightSquared’s proposed transmission structure will adversely impact GPS and Inmarsat signals along our coastlines, both of which are critical to marine operations.

Expert Advice: GNSS Interference, Detection, and Mitigation

May 1, 2011

Interference, detection, and mitigation — these have become topics of paramount importance to the GNSS community recently, surpassing at times even those old familiar standards accuracy, availability, and integrity. In March, a large expert audience attended a GNSS Interference, Detection, and Mitigation (IDM) conference at the United Kingdom’s National Physical Laboratory near London. My conclusions first, followed by reportage of the details.
