The System: U.S. DoD, DoT Tell FCC No LightSquared

February 1, 2012By

Ashton Carter, U.S. deputy secretary for Defense, and John Porcari, deputy secretary for Transportation, have written an official letter to the assistant secretary of Commerce stating that “there appear to be no practical solutions or mitigations that would permit the LightSquared broadband service.” Carter and Porcari are co-chairs of the National Executive Committee for Space-Based Positioning, Navigation, and Timing.

Da Capo: Pardon Me, Boy, Is That the Galileo Choo Choo?

February 1, 2012By

Our Paris correspondent, Ms. Axelle Pomies, writes that “The Galileo Train is about to depart, but European GNSS applications incentives are still at the station.” “Despite a vast potential for industry growth and new jobs in Europe,” she continues, “European government bodies are not taking up the challenge. The budget dedicated to GNSS application research in European Commission FP7 was... read more

Patch Antennas for the New GNSS

February 1, 2012By

Small ceramic patch elements offer nearly perfect single-frequency receive characteristics and have become the standard for GPS L1 antennas. However, the new generation of GNSS receivers now being introduced track many satellites in multiple constellations. Are these narrow-band devices up to the task for wider bandwidths? read more

Out in Front: When the Gavel Comes Down

February 1, 2012By

Perhaps you don’t track suspected criminals in your spare time, nor do you design or supply a GNSS product that does so. Still, the fresh Supreme Court ruling on GPS use for this purpose reverberates for you, in ways yet unknown. The most interesting part of the court’s ruling pops up in a somewhat open-ended “what if” comment concerning future issues that at least one justice thinks the court should address. read more

FCC Asks If You and GPS Should Be Protected from Interference

January 30, 2012By

“We invite comment on LightSquared’s petition, and establish a pleading cycle.” Thus spake the Federal Communications Commission (FCC), groping for a way forward in the ongoing LightSquared/GPS conflict. The FCC has opened an Internet docket for public comment on the LightSquared position that GPS users and receivers “do not merit legal protection from interference” created by LightSquared. The FCC asks... read more

Let’s Hear It for the Supremes!

January 24, 2012By

Last week’s Supreme Court ruling on GPS use for tracking criminal suspects makes U.S. law clear on this issue going forward, but it does not address tracking for commercial aspects. One U.S. newspaper editorialized, “the unanimous decision failed to resolve troubling questions about the privacy rights of Americans in the face of intrusive modern surveillance technology.” The privacy picture in other large markets — Europe, Japan, Korea, Russia, China, and elsewhere — remains even less clear. If GNSS should be perceived as a tool of Big Brother (government) or Big Broker (industry selling and buying consumer location data), then all navigation systems acquire a big PR problem, which translates into big funding and modernization problems. read more

Facts, Law, Table, Pound, Hand

January 16, 2012By

So it has come to this. LightSquared officers want the FCC to investigate Brad Parkinson. Senator Joe McCarthy is not a good look for them. A young attorney of my acquaintance, who also happens to be a contributing editor to this magazine, wrote me in this regard: “Lawyers have an old saying — when you don’t have the law on... read more

Out in Front: Big Bang Cheery

January 1, 2012By

A supersize bunch of pent-up GNSS just bust out all over. GLONASS is fully operational for the first time in more than 15 years. At least one Galileo in-orbit validation satellite broadcasts the new E1 and E5 signals, maybe both satellites by the time you read this. Compass has completed its regional navigation constellation. The first GPS III satellite testbed arrived at its integration and testing site in Colorado. The Russian SBAS is climbing back onto the air again. And QZSS has been quietly making progress, almost unnoticed. read more
