Out in Front: A Pawn in Their Game

August 1, 2011By

Maybe we got played. But we put up a good fight. We really had no option to do anything but fight. So we did, and we’re still fighting the LightSquared attack on the GPS signal. It’s not over yet, not by a long shot. Suspicions now creep in that the attack may have been a feint, that the company never really intended to do what it threatened: broadcast a very powerful signal from ground towers, on a frequency immediately adjacent to the GPS signal. LightSquared had its eye on another prize instead. read more

Once again, developments in the news outpaced print technology’s ability to keep up in the LightSquared saga. Shortly after the July issue went to press on June 27, the TWG final report appeared on June 30. Thus you readers, who received the magazine circa July 15, held old news in your hands. Likely this will occur again. read more

Expert Advice: Who Won?

August 1, 2011By

Thousands of man hours and millions of dollars later, we finally have the 975-page GPS Technical Working Group (TWG) report, confirming what five minutes of back-of-the-envelope calculation predicted. Hooray for our side, good job GPS Industry Council; we’ve won the war and the foe is vanquished, never to brighten our skies again. Well, maybe. LightSquared is now bypassing the Federal Communications Commission (FCC) and submitting technical papers directly to the United Nation’s International Telecommunications Union (ITU) Working Party that handles mobile satellite services (MSS) and radio determination satellite service (RDSS spectrum) and orbits (ITU-R WP 4C). read more

LightSquared: Comments I Submitted to the FCC

July 28, 2011By

Okay, folks, this is where the rubber meets the road. The FCC LightSquared public comment period ends this Saturday. If you use GPS, it would be very wise to submit your comments today. Don't expect the FCC to make a rational decision. LightSquared has an amazing amount of political influence, and you can see that in the support they receive from state legislators, mayors, chiefs of police, etc. In this article, I'll show you how to submit your comments to the FCC in just five minutes. I'll also show comments I'm submitting to the FCC. read more

To Solve LightSquared Issue, Javad Ashjaee Calls for End to P-Code Encryption

July 15, 2011By

To solve the LightSquared versus GPS controversy, Javad Ashjaee, president and CEO of JAVAD GNSS, has appealed directly to President Obama to discontinue the encryption of P-code, the restricted military GPS signal. His comments came in the context of the LightSquared/GPS interference imbroglio, as part of his solution to the conflict over spectrum. “This policy is not helping national security. It is hurting both precision users and the broadband project. We need more broadband, for global, fast, and inexpensive real-time kinematic (RTK) GPS.” read more

LightSquared: 1, High-Precision GPS: 0

July 14, 2011By

At stake is the high-precision GPS industry as we know it. If LightSquared's current proposal is approved by the FCC, it will render tens of thousands, and possibly hundreds of thousands of GPS receivers obsolete starting as early as next year. The FCC is accepting public comments until July 30 and replies to those comments until August 15. After the public comment period is closed, the FCC can render a decision at any time. Last weekend, I spoke alongside LightSquared and the Coalition to Save Our GPS in a two-hour panel discussion at the Esri Survey Summit in San Diego. Here's my report. read more
