What Do You Know? What’s Your CEP?

December 3, 2012By

Here is the accuracy and estimation game played by 208 guests at GPS World’s Leadership Dinner in Nashville, Tennessee, on Thursday evening, September 20. Take a gander at the rules that follow, and then try your skill at the nine questions. To play fair, do not use Google or any other research, reference, or resource. Dinner guests were honor-bound not... read more

Letter to the Editor: Our First Mistake

December 1, 2012By

Our first mistake is to presume an environment of perfection and security. Nothing is foolproof and spoof-free. Every product or service is an envelope of packaging that can be opened, peeled back, reversed engineered, and replicated. I have seen “ultimate security” defeated repeatedly. GPS is no exception, of course. We put our signatures and seals on these things; enterprising competitors,... read more

Out in Front: If We Only Know Then What We Don’t Know Now

December 1, 2012By

Some of you have been asking questions, and while it is generally our business to provide answers, in this case I simply show these questions back to you, for instructive purposes.

  By Alan Cameron.   It was thirty years ago today, Cheremisin taught the band to play. They’ve been going in and out of style, but they’re guaranteed to raise a smile. So may I introduce to you the constellation here for years, Vladimir Putin’s GLObal NAv Sat System! While in our booth at INTERGEO in Hanover last month, I... read more

Letter to the Editor: Using One Part of GPS, Ignoring Another

October 1, 2012By

The article “Drone Hack” in the August issue of GPS World and Todd Humphreys’ testimony before a House Subcommittee overseeing the Department of Homeland Security cited results of a spoofing experiment Humphreys conducted with University of Texas colleagues, demonstrating that a drone helicopter, navigating principally on the civil GPS signal, could have its vertical channel spoofed, causing it to descend.... read more

Out in Front: The Bronze Prize for Golden Success

October 1, 2012By

We have heard it before, in various fora and in various forms: the GPS program is a victim of its own success. Because the satellites are living so long, launches of new, modernized space vehicles get deferred. And deferred. And deferred. The U.S. Congress meanwhile, for whom “defer” is a code to live by, happily pounces on this as an... read more

Out in Front: Live Free or Die Hard

August 1, 2012By

The 2007 action film of that name concerns a domestic criminal plot, disguised as a terrorist attack upon U.S. infrastructure: an Internet-based hack into Federal Bureau of Investigation computers, the transportation infrastructure, the stock market, national video broadcast channels, the utility power grid, the National Security Agency, and the Department of Defense nerve center. One of the film’s two heroes recognizes this as a fire sale, an attack upon the nation’s computer controls, an attack in which “everything must go.” read more
