Representatives from a wide variety of industries, companies and associations, including AOPA and GAMA, have joined together to form the Coalition To Save Our GPS to resolve a “serious threat” to GPS.

A panel of experts, selected jointly by the GPS Industry Council and LightSquared Corp., is currently determining whether LightSquared’s proposed NAS-wide network of 40,000 powerful ground stations transmitting voice and Internet traffic could interfere with and potentially jam GPS receivers operating within their own FCC-protected frequency band.
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.
Garmin has rolled out a sub-$16,000 avionics system that’s certified for installation in nearly 600 Class I and II Part 23 airplanes (defined as singles and twins weighing less than 6,000 pounds). The Garmin G500 avionics system, introduced at last month’s EAA AirVenture in Oshkosh, Wis., includes primary and multifunction displays mounted in a single bezel that can slide into the opening previously occupied by an instrument six-pack.
Garmin’s GPSmap 696 is a capable and feature-filled portable GPS navigator that doubles as a Class 1 or 2 electronic flight bag (EFB) with the ability to display weather, terrain, approach charts and airways. While the 696 displays own-ship position on moving maps and SafeTaxi airport diagrams, potential buyers should know that it does not do so on approach charts.
Accord Technology (Booth No. 520) is promoting its NexNav line of GPS WAAS receiver technology, which supports LP/LPV approaches and new ADS-B standards. A joint venture of Accord Software & Systems of Bangalore, India, and NexGen Avionics, Accord is also announcing appointments of R. Shenoy Manur, CEO; Hal Adams, COO; and Randy Shimon, v-p, engineering and compliance.
Elm Creek Partners has acquired avionics and navigation system supplier FreeFlight Systems (Booth No. 1481). The new executive management team, led by CEO Tim Taylor and COO Robert Schneier, assumed responsibility July 15.
