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. They come from the 2012 State of the Industry Survey, reported in the September issue. In that survey, we posed one question whose results were not reflected in that... read more

Getting to Z: Indoor Positioning with GPS

November 28, 2012By

By Alan Cameron In this column, I normally write about satellites, signals, and space (as in outer), and the policies or controversies pertaining to those entities. This week we are headed indoors. Inner space, where GNSS has difficulties going, but must go, somehow, to prove itself commercially and governmentally. To do so, it needs powerful friends. The most rigorous indoor... read more

Good News and Plenty of It

GPS IIF

Firing on all cylinders — to use a slightly outmoded technological metaphor — GNSS moved forward on virtually every front in the past month. GPS made major advances both on the ground and in space, Galileo took a giant step, Compass continued on its roll, GLONASS has good news pending in only a day or two (knock on wood), and... read more

October 3, 2012By

At the magazine’s annual Leadership Dinner, held during the ION-GNSS Conference, we gave the first GNSS Leadership Awards to four individuals for their respective work in the four fields of satellites, signals, services, and products. We asked each recipient to give us a vision of the future: upcoming work, whether that’s something they plan to undertake or they think someone... 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
