Out in Front: Ruminations Upon a Technical Program

June 1, 2013By

The Institute of Navigation’s (ION’s) advance program for the 2013 GNSS+ conference in September arrived in the mail the other day, and was avidly consumed. The technical sessions of this gathering are prime hunting ground for presentations that later become articles in this magazine, as are, to lesser extent, those of the European Navigation Conference, the Joint Navigation Conference, CTIA,... read more

Out in Front: The System, Simulated

May 1, 2013By

Wealth, breadth, and depth. That’s what this issue brings you, in signal simulation- and testing-related content. Unfortunately, the wealth on offer has to large extent elbowed out our two news sections, The Business and The System. The former is given short shrift in this issue and the latter even shorter herewith, in pithy precis with website shortcuts. And our apologies.... read more

Out in Front: Galileo’s World

It’s been a long time coming. With the capability to make a position fix from four signal-broadcasting satellites, we can now say that Galileo has truly arrived. Of course, this is only one of many milestones (excuse me, kilometer markers) along the way, a trajectory that could be bounded at 23 years and counting, or possibly longer. Let’s not forget,... read more

Out in Front: The Semi-Private Life of Waldorf Twitty

March 1, 2013By

We’re going through!” The Captain’s voice was like thin slate breaking. He wore combat fatigues with a dusty beret. “We can’t make it, sir. 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

Out in Front: Stand By to Capsize

February 1, 2013By

We have reached our tipping point, say the seven U.S. military Joint Chiefs of Staff in a January 14 letter to Senator Carl Levin, chairman of the U.S. Senate Committee on Armed Services. “We are on the brink of creating a hollow force,” they continue. 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. It is impossible to tell as this magazine goes to press in December just where we may find... read more

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.

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
