Following a certification and verification process, the European Commission approved the European Geostationary Navigation Overlay Service (Egnos) “safety-of-life” service for aviation last month. Egnos is closely similar to, and compatible with, the U.S. Waas satellite-based augmentation system that corrects timing errors in GPS signals, enabling GPS precision approaches and shorter, more-direct routes.

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.

Following a certification and verification process, the European Commission approved the European Geostationary Navigation Overlay Service (Egnos) “safety-of-life” service for aviation last Wednesday. Egnos is closely similar to, and compatible with, the U.S. Waas satellite-based augmentation system that corrects timing errors in GPS signals, making it more accurate.

Whether for safety, economy or to meet ICAO Flight Operations Quality Assurance (FOQA) standards, helicopter operators are showing increased interest in capturing and analyzing flight data. Spidertracks (Booth No. 4854), based in Palmerstown North, New Zealand, offers a global satellite-based system for fleet operators that tracks equipped aircraft in real time and records movements and flight data for later analysis.

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.
