March 1, 2013By

They’re laying down fire too heavy, if you ask me.” “I’m not asking you, lieutenant,” said the Captain. “Go to overdrive!” The throb of the diesel Stryker increased: cha-rugga-rugga-rugga. He surveyed the rocky defile ahead. “Throw... read more

By this they mean that the military of the size that they are required to... read more

Out in Front: Let the Chips Fall

January 1, 2013By

We either continue to totter at the brink of a global financial precipice, or we sit crumpled on the canyon floor far below, peering skyward, wondering what might have been, and resolving to pick up what pieces we can and carry on.

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

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
