From our friends over at BoatU.S.;
As a result of a new proposal to use radio bandwidth right next to the existing GPS service, the future reliability of the GPS system across the United States is now in question. We encourage you to contact the FCC during a short 30-day public comment period, to help them understand the public’s need for continued, reliable GPS signals for safe navigation on boats, in cars, and for so many other daily uses.
Background: Earlier this year, the Federal Communications Commission (FCC) gave conditional approval to a private company, LightSquared, to begin a nationwide broadband service adjacent to the radio spectrum used for GPS. After concerns from user groups (including BoatU.S.), the FCC required significant testing and a report for potential conflicts with aviation, cellular, navigation, and four other GPS uses before this proposal could move forward. In that June 30th report the navigation sub-team concluded “that all phases of the LightSquared deployment plan will result in widespread harmful interference to GPS signals and service and that mitigation is not possible.”

In 2010 the US Coast Guard shut down Loran, leaving mariners using electronic navigation to rely solely on GPS. Now, this fast-moving threat to GPS could pull the plug on our ability to safel navigate within the U.S. Public comments on LightSquared’s proposal will be taken until Saturday, July 30, 2011. Following that, the FCC will make a determination on what this private company can do with this vital public resource.
