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

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

U.S. Defense, Transportation Say Keep Wireless Comm Away from L-Band

July 9, 2011By

The U.S. Departments of Defense and Transportation declared their strong opposition to the LightSquared proposal for a nationwide broadband service immediately adjacent to GPS signals. They asked the FCC to withhold authorization for the company to commence commercial service per its proposed deployment of a terrestrial service within the 1525-1559 MHz bands. read more

Final Report of FCC Working Group: Lose LightSquared from L-Band

July 6, 2011By

“Based on the analysis performed, LightSquared should not be permitted to use the L-Band spectrum for a densely-deployed, non-integrated terrestrial-only network. Such a network would cause unacceptable interference to GPS operations, wiping out an installed base of over 500 million units used in a wide array of public safety, aviation, industrial and consumer applications. While mitigation techniques utilizing filters were discussed in theory, they could not be tested as part of the WG effort because filters do not exist, even in prototypes. No information considered by the WG demonstrated that any mitigation techniques — other than relocation of the proposed terrestrial network to an alternative band — would be successful.” (From the U.S. GPS Industry Council's overview of the WG report) read more

“The Economic Benefits of Commercial GPS Use in the United States and the Costs of Potential Disruption” was presented by Nam D. Pham, Ph.D., of NDP Consulting, during a June 21 webinar sponsored by the Coalition to Save Our GPS. The report states: “The direct economic benefits of GPS technology on commercial GPS users are estimated to be over $67.6 billion per year in the United States. read more

Out in Front: The Daughter of Time

July 1, 2011By

"Truth,” wrote Sir Francis Bacon, “is the daughter of time.” He meant that any account, repeated often enough by different people in different places, at different junctures, eventually becomes accepted as historical fact, or truth, by those with no direct knowledge of the matter. That’s why it is so important to repudiate and expose lies at every encounter. Never, ever let one pass. Even when it’s the same one that you dispelled yesterday — or thought you had taken care of. One thing about liars, they keep coming back. They don’t give up. Would you give up, if you had $20 billion at stake? read more
