Over the next three months, a panel of 14 experts will test and analyze whether LightSquared's proposal to transmit Internet data from a nationwide network of 40,000 high-powered ground stations will jam very low powered GPS signals operating in the immediately adjacent GPS frequency band.
Small, inexpensive GPS jammers carried by truckers have caused the occasional shutdown of the Laas test installation at Newark Airport. The devices, powered by simply plugging into the cigarette lighter, are intended to foil interrogations of the truck's remotely installed GPS and its coupled cellphone by the trucking company's dispatcher to check on the vehicleπs location and progress.
Garmin reports that LightSquared’s proposed nationwide broadband Internet service could seriously interfere with GPS signals. As a result of this and other filed objections, the FCC is withholding LightSquared’s operational approval until a three-month independent expert analysis agrees that this will not occur.
Phoenix-based Accord Technologies is at Heli-Expo (Booth No. 7839) to acquaint OEMs, avionics developers and modification centers with its NexNav modular GPS receivers.
The company’s small, low-power receivers are available as circuit card assemblies (CCA) for avionics OEM hosting or as LRUs for aircraft installations. They will support ADS-B, all normal GPS procedures and precision approach requirements.
Accord’s NexNav technology is compatible with Satellite Based Augmentation Systems (SBAS) including WAAS, European EGNOS, Japan’s MTSAT and GAGAN in India.
The U.S. Departments of Defense, Transportation, Commerce and Homeland Security, as well as the civil GPS Industry Council–of which NBAA is a member–have filed objections with the FCC over a new satellite-enabled cellular broadband service from LightSquared.
Several years ago, when satellites were being touted as aviation’s sole means of navigation from takeoff to touchdown, former FAA Administrator Langhorne Bond painted a picture of a dark winter’s night with below-limits weather up and down the east coast. In that scenario, he stated, terrorist GPS jammers could become “weapons of mass destruction.” The FAA shrugged it off as unfounded speculation.
GPS designers understood from the beginning that the system’s weak signals would be vulnerable to inadvertent or deliberate interference, with the threat formally recognized by the DOT’s Volpe Center in Cambridge, Mass., on Sept. 10, 2001�one day before 9/11. Since that time, the Department of Defense has run annual all-altitude tests�over the Western U.S.
Pilots who have problems obtaining Jeppesen charts or believe Jeppesen holds a monopoly on the distribution of IFR approach and en route charts might be interested to know that there are alternatives. Jeppesen isn’t the only game in town, although the company has made an art of crafting its own approach charts and not simply repurposing government charts.
328 Support Services has announced the new 328DBJ model, with an updated interior, as the replacement aircraft for the Envoy version of the jet. The new 328DBJ forward cabin was redesigned to deliver an additional half-meter of cabin space and includes electric window blinds and slim-line passenger service units (PSU).
Whether an aircraft is operated under Part 91, 135 or 121, the Federal Aviation Regulations require that maintenance discrepancies be repaired before the next flight unless there are appropriate provisions for deferring that maintenance and those procedures are followed.
