Mark, good info, and between this and SOPA Washington is on a Track to screw up both GPS and the Internet as we know it. Crazy isn't it? Sent from my iPad On Feb 2, 2012, at 4:04 PM, "Roberta Dvorscak" <edarts93@earthlink.net> wrote:
My qualifications to speak on this subject come from working in the land surveying business for the past 15 years. All of us in land surveying who depend on GPS for our livelihood are very concerned. If Lightsquared gets approved GPS will go down in a wide area around their transmission towers. A test was recently done on their proposal in Nevada and it totally obliterated the GPS signal. No position information could be obtained anywhere near the test area. LightSquared's proposal that everybody purchase new equipment that filters out their signal is ridiculous. They need to find a frequency that is not adjacent to GPS or shelve their plan because it is incompatible with current civil use of GPS. This opinion is not from a PHD but from a real world GPS user. More information from the pros below and a link to a website with further info.

December 14, 2011 WASHINGTON -- Today, a government technical group reviewed the findings from last month's testing of LightSquared's proposal to provide new broadband service. The final test report will be sent to the National Telecommunications and Information Administration (NTIA), which advises the President on telecommunications policy, and represents federal agencies to the Federal Communications Commission (FCC).
Preliminary analysis of the test findings found no significant interference with cellular phones. However, the testing did show that LightSquared signals caused harmful interference to the majority of other tested general
