WASHINGTON – Sen. Chuck Grassley of Iowa continues to seek answers regarding the Federal Communications Commission (FCC) and its dealings with the firm, LightSquared.

This week, Grassley wrote separate letters to the top investor in and the chief executive of the company, seeking materials that would shed light on why the agency has allowed the company to advance wireless broadband plans, despite serious concerns of technical interference with the GPS systems used widely in military, aviation and emergency response venues.

So far, the agency has refused to provide the public with insight into its approval process so far.

“The public’s business ought to be public,” Grassley said.

Grassley’s letters are available here and here.

One comment on “Senator Chuck Grassley Continues to Pursue Information on LightSquared, Agency Interaction
  1. Keith Peshak says:

    LightSquared shuts down GPS receivers because the powerful signal (15,750 watts, or, maybe ½ that) just right near GPS receivers (up to many miles away) saturates the antenna amplifier in the GPS receiver trying to receive about 300 watts from about 11,000 miles away. No filter on LightSquared transmitters can prevent that. Need a filter on the GPS receiver after the patch before the gain stage to ground out the LightSquared off band signal. Here is ours: http://www.imcsd.com $1200 and the size of a brick and NOT a complete solution. Sanjiv Ahuja has said he has one for 30 cents. We are waiting to see one. Javad says they have a better GPS. We are waiting to see one. Either way, you all get to buy a new GPS.

    Another way is to alter the LightSquared protocol, to contain “holes” that GPS can listen through. Doug Smith who is Chief Network Officer for LightSquared says “…I do not intend to follow up with you regarding your proposal” and “Please understand we have received hundreds of offers to solve our issue and simply do not have time to engage everyone.” That option does not have you all buying a new GPS.
