In your March editorial, “The Fire Next Time,” you ask for suggestions to protect against another LightSquared encroachment. The solution is remarkably simple. Just let the same bandwidth be used for space downlink as it was originally intended. That would be both innocuous to GPS receivers...More>>

‘We have virtually no defense against the cyberattacks that are targeting us now, and will be in the future.” Richard Clarke served three U.S. presidents as counterterrorism czar. He wrote a fascinating — and terrorizing — article in the April issue of Smithsonian magazine, from which comes...More>>

Advanced low-frequency (LF) signals are back on the air in North America, with live testing of a wide-area precise-timing solution. Initial tests include a comprehensive pallet of signals, including eLoran, that are being evaluated for their ability to provide a robust, wide-area, wireless...More>>

We have turned back the LightSquared effort to establish a threatening beachhead adjacent to GPS spectrum bands. Having expended many millions, we can now return to our business, secure in having demonstrated both our rights and our rightness. No. We cannot afford to do that.More>>

Perhaps you don’t track suspected criminals in your spare time, nor do you design or supply a GNSS product that does so. Still, the fresh Supreme Court ruling on GPS use for this purpose reverberates for you, in ways yet unknown. The most interesting part of the court’s ruling pops up in a...More>>

A supersize bunch of pent-up GNSS just bust out all over. GLONASS is fully operational for the first time in more than 15 years. At least one Galileo in-orbit validation satellite broadcasts the new E1 and E5 signals, maybe both satellites by the time you read this. Compass has completed its...More>>

According to the official test results, 300 million inexpensive GPS receivers in cell phones do not get affected by LightSquared, but the very expensive military GPS receivers that are supposed to be battle hardened do!More>>

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...More>>

Expecting guidance from FCC regulators by year’s end? LightSquared purports to do so, but a more measured evaluation finds a December decision unlikely. The current test cycle — hopefully not the final one — just reached its end on November 4 at White Sands Missile Range, under the Air...More>>

In this hour of crisis, in this hour of need, I would recall for you the immortal words of the Brotherhood of Man, as reprised here by their disciples, Sonny and Cher: For united we stand, Divided we fall, And if our backs should ever be against the wall, We’ll be together, Together, you and I....More>>
