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.

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.

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.
