House Science Committee Reschedules LightSquared GPS Interference Hearing

Now that Hurricane Irene and summer vacation have blown over, members of Congress are returning to Washington, D.C., to resume — among other things — addressing the question of LightSquared’s interference to GNSS.

A hearing originally scheduled for August 3 is back on the agenda for the U.S. House Science, Space, and Technology Committee and now scheduled for 2 to 4 p.m. on September 8.

2SOPS Takes Over IIF-2, Moves to Replace SVN-30 with Spare

Command and control of the second GPS Block IIF satellite has been turned over to the 50th Space Wing’s 2nd Space Operations Squadron (2SOP) at Schriever Air Force Base, Colorado, today (August 22, 2011).   

The Space and Missile Systems Center’s (SMC) GPS Directorate, located at Los Angeles Air Force Base, retained control of the satellite during a 30-day on-orbit checkout period before the hand-off to 2 SOPS.

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."

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.
