Expert Advice: Energy Production Concerns about LightSquared

July 1, 2011

Dear Chairman Genachowski: The National Ocean Industries Association (NOIA), which represents approximately 270 member companies involved in outer continental shelf (OCS) energy production throughout the United States, is gravely concerned over the pending allocation of Mobile Satellite Services (MSS) spectrum to LightSquared, Inc. for terrestrial high-powered transmissions. LightSquared’s proposed transmission structure will adversely impact GPS and Inmarsat signals along our coastlines, both of which are critical to marine operations.

LightSquared Goes Global; GLONASS, Galileo May Be at Risk, Too

June 28, 2011

Recent events, some of them summarized here, may appear to have dealt setbacks to LightSquared, the boundless opportunist of wireless broadband that just happens to interfere with GPS. But the company has not run out of moves yet. Would you, if you had $20 billion at stake? The latest gambit, led by lawyers and cloaked in jargon, appears to be an end-run around the U.S. government to appeal to the International Telecommunications Union, which has ultimate and international authority over spectrum. Watch out, GLONASS and Galileo — and U.S. troops operating in foreign theaters.

LightSquared: High-Precision Receivers Are Collateral Damage

June 21, 2011

Originally, the LightSquared/GPS Technical Working Group’s (TWG) report was due to the FCC on June 15. LightSquared requested from the FCC, and received, a two-week extension to submit their report. Three days later, LightSquared announced they found a solution to the GPS interference problem. Their proposed solution is not good news for the high-precision GPS user community.

LightSquared, FCC Rebuttals Distort Record

June 14, 2011

A claim frequently made by LightSquared spokesperson Jeff Carlisle, and recently by FCC chairman Julius Genachowski, that the GPS industry knew long ago about LightSquared’s plan for powerful terrestrial transmitters, would be a telling point — if it were true. But it is not. The verifiable fact is that the GPS industry knew about and agreed to a plan by a previous version of the company, for a different purpose, with a different business concept, and employing a completely different technological approach, one that would not have harmed GPS transmissions and disabled GPS users the way the current plan does. Calling the 2010 LightSquared plan the same as the 2003 Motient plan is running a wolf in sheep’s clothing.

LightSquared: It’s Worse than You Think

May 18, 2011

Tired of hearing about LightSquared? Think it’s a bunch of panicking journalists hungry for something to write about?
Listen, it usually takes a lot to get the hairs standing up on the back of my neck. On the LightSquared issue, they are at full attention. Why?

Q&A from L5 and LightSquared Webinars

May 5, 2011

In late March, I conducted a webinar titled “A Closer Look at L5: The Future of High-Precision GNSS,” in which I discussed the impact that the new GPS L5 signal/frequency may have on high-precision users. Then, in April I was part of a discussion panel-format webinar titled “LightSquared: Our Story So Far.” Many questions and comments arose from both webinars, and I’ll attempt to address those in this column.

Out in Front: Blinded by the Light

May 1, 2011

To illustrate the fix we’re in, Logan Scott offered this analogy for out-of-band interference during the April webinar, “LightSquared and GPS: Our Story So Far.” We’re driving at night and come upon a bicylist with one of those little flashing lights. That’s the GPS signal. So far, so safe. We know the bicyclist’s position. Then around the bend comes a truck with its headlights on high-beam, in the adjacent lane, but brights set at our eye level. That’s the LightSquared signal. Where’s the bicyclist? Uh oh.
