LightSquared, FCC Appear to Align on GPS Receiver Standards in Continuing Spectrum Battle

In one of three separate filings on Friday (September 28, 2012) would-be broadband provider LightSquared asked the Federal Communications Commission (FCC) to set “operating parameters” leading to “revised technical rules” to enable it to operate in the lower of the two frequency bands where tests last year showed its operations would interfere with GPS.

Those rules and parameters should, the filing intimated, include standards for GPS receivers.

GPS Civil Funding

GPS Civil Funding

The Federal Aviation Administration (FAA) has told those awaiting their slice of the GPS civil program budget that the funds are on the way.

The money, which is supposed to support that portion of the GPS program springing from the needs of civilian users, has been held up for months. In fact, as of late August — with less than 40 days left to go in the fiscal year — the money had not been transferred to either the military’s GPS Directorate or the National Coordination Office (NCO) for Space-Based Positioning, Navigation, and Timing (PNT).
