Citing European Space Agency (ESA) studies that showed “harmful interference” to Galileo receivers operating up to 1,000 kilometers from LightSquared base stations, a European Commission (EC) official has told the Federal Communications Commission (FCC) about his “deep concerns” about the wireless broadband company’s terrestrial transmissions in the 1525–1559 MHz band next to L1 GNSS frequencies.

[updated July 16] Boeing has received the first on-orbit signals from the second of 12 GPS Block IIF satellites it is building for the U.S. Air Force. GPS IIF-2, renamed Space Vehicle Number 63 (SVN-63), is functioning normally and ready to begin on-orbit maneuvers and operational testing.
After two postponements, the second GPS Block IIF satellite launched successfully from Cape Canaveral at 2:41 a.m. EDT on July 16. A video of the launch was posted on YouTube and can be viewed here.

Lockheed Martin has announced the successful, on-schedule completion of a system design review (SDR) for the second-phase of next-generation GPS satellite development, the IIIB increment.
The company’s Space Systems division in Newtown, Pennsylvania, is under contract to produce the first two of a planned eight GPS IIIA satellites, with first launch projected for 2014. The contract includes a Capability Insertion Program (CIP) designed to mature technologies and perform rigorous systems engineering for future GPS III increments.

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.
