LightSquared’s planned nationwide 4G broadband network got yet another reprieve from Sprint today. Last year, Sprint agreed to provide $15 billion to LightSquared for infrastructure needs, with one condition: LightSquared must obtain FCC approval by Dec. 31, 2011. The FCC didn’t come through–saying LightSquared has yet to prove its transmissions will not interfere with GPS signals–but last month Sprint extended its offer until the end of this month. And with barely 12 hours to spare, Sprint again extended this until mid-March.

“It is the unanimous conclusion of the test findings by the National Space-Based Positioning, Navigation and Timing (PNT) Executive Committee (ExCom) agencies that both LightSquared’s original and modified plans for its proposed mobile network would cause harmful interference to many GPS receivers,” the committee wrote in a letter sent to the National Telecommunications and Information Administration (NTIA) on Friday. The PNT ExCom–composed of nine U.S.

One of the supreme ironies of the ongoing LightSquared saga is that the company’s efforts to promote its nationwide email initiative are not helped when emails about its own activities, written by U.S. government bureaucrats, become public under Freedom of Information legislation.

LightSquared reported yesterday that results of testing by an independent laboratory “confirmed that several major high-precision [GPS] receivers…are 100-percent compatible with LightSquared’s network.” LightSquared is seeking government approval to

LightSquared is coming under pressure from several separate directions, as opponents to its plans provide more specific support to their positions on legal, financial and technical issues.

Signals that can be jammed

One of the pleasures of attending the many aviation trade shows on our annual to-do list is the opportunity to see new aircraft, products and people.
