Expert Advice: Soldiers and Civilian GPS: Dangerous (and Deadly?) Expediency

April 1, 2012By

An old adage says, “Be careful what you wish for, you might get it.” That is particularly relevant in today’s world of GPS and the positioning, navigation, and timing (PNT) dependencies it has created. In business, it’s all about location, and in military circles, something called real-time situational awareness, driven by the ready availability of PNT from GPS. However, it has been reported (and validated by experience) that U.S. soldiers believe that the GPS equipment they are issued through official channels is too big, too heavy, uses too many batteries, and is old-looking and not sexy like the multi-color, multi-app personal electronics and smart phones they are accustomed to at home. read more

December 1, 2011By

I’ll be the first to say that I don’t know how Washington works. I don’t know if Washington works, but that’s another story. Lacking that knowledge, and a competent lawyer to pepper my filings with the requisite “Vaughn v. Rosen, 484 F.2d 820 (D.C. Cir. 1973), cert. denied, 415 U.S. 977 (1972) . . . claims of nonsegregability must be made with the same degree of detail” language, all my Freedom of Information Act (FOIA) requests for agency communications to the National Telecommunications Administration (NTIA) failed. My FOIA won-lost record stands at 0–7. read more

Expert Advice: EPIC Happening — Europe’s PNT Industry Council

September 1, 2011By

We have the United States GPS Industry Council, the Japan GPS Council, and the Korean GNSS Technology Council. Anything missing?

The System: An L5 Surprise

August 1, 2010By

Researchers at the German Aerospace Center say they have found a small variance in the L5 signal on IIF-1. The signal variation results in no more than a 5-centimeter error with a predictable periodicity of about six hours. The GPS Wing is studying the issue and expects to resolve it before setting the satellite healthy, in another month or so according to the schedule. read more

Expert Advice: Remembering. And Resolving

August 1, 2010By

Few outside the position, navigation, and timing (PNT) community will also recall that the day before the 9/11 attacks, the U.S. government released a landmark document that described the vulnerabilities of services provided by GPS to disruption, whether by attack or inadvertent interference. The Department of Transportation Volpe Center’s GPS vulnerability assessment recommended that services utilizing GPS-provided PNT seek alternative sources of these services. What decisions and actions have the findings and recommendations of this report promoted? The answer is most disturbing. read more
