LightSquared Charges That GPS Receiver Manufacturers “Ignore” DoD Standards

LightSquared has opened a new rhetorical front in its battle with the GPS community over the company’s efforts to convert L-band frequencies into terrestrial wireless broadband services: claiming in an August 11 letter to the Federal Communications Commission (FCC) that receiver manufacturers “chose to ignore” Department of Defense (DoD) standards.

In response, the Coalition to Save Our GPS, a group of GPS receiver manufacturers opposed to LightSquared’s plans, called the company’s filing an act of "desperation."

The Fire Next Time

What have we learned from the LightSquared fiasco?

Aside from the fact that someone gambling with other people’s money, with friends in high places benefiting from his largesse, can make the law stand on its head and our hair stand on end.

But then, we already knew that.

Just because the forces behind the broadband cellular company, Philip Falcone and Harbinger Investments, made their money by betting against the housing bubble doesn’t take away from the fact that they represent the same crew who helped take down the world economy in 2007.

FCC Invites Comment on LightSquared Interference to GPS

Individuals and organizations wishing to comment on the recently released technical working group (TWG) report on LightSquared’s interference to GPS as well as the company’s proposal for dealing with the problem have until July 30 to submit statements to the Federal Communications Commission (FCC).

In a release dated June 30, the agency noted that the TWG effort “identified significant technical issues” related to potential LightSquared interference in the upper portion of the L-Band, next to the band used by GPS.

Interference can pose a threat to the reception of GNSS signals in a variety of ways. Even low-level signals have the potential to interfere with GNSS receivers, which require very high sensitivity for acceptable performance due to the extremely low received GPS signal power at the Earth’s surface.
