December 7, 2011By

At the end of every year, I title this column Directions, in which I discuss significant developments, trends, technologies, companies, and so on, in the GNSS industry.

A dramatic increase over the next five years to roughly 100 GNSS satellites in the skies over Asia and Oceania makes that region the fastest growing area in GNSS. The Multi-GNSS Asia (MGA) initiative, a cooperative international demonstration campaign, seeks to take full advantage of this scientific and technical windfall, gaining early experience with the new signals and services of multi-constellation GNSS. read more

Expert Advice: Test-Based Civil Receiver Certification

December 1, 2011By

Disaster-preparedness plans recognize the individual’s role in his or her own survival. When storms approach, have water, food, and basic survival gear on hand. It takes time for help to arrive. The civil GPS industry faces an oncoming storm of interference, and the receiver is the first line of defense. As we integrate GPS into all facets of our lives and infrastructure, we become more subject to disruptions, both unintentional and intentional. Newark International Airport now sees several jamming events per day. In Taiwan, one airport experiences an average of 117 events per day! read more

Out in Front: Feds Playing Footsie

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

The Hits and the Misses

November 29, 2011By

LONDON — Technical conferences usually feature hits: advances in technology, new form factors, improved signal processing. But the opening day of the European Navigation Conference in London has dwelt instead on misses: vulnerabilities, threats, weaknesses that leave GNSS increasingly open to attack and disruption.
