There’s a new way to fix long-standing noise and emissions problems at airports that are surrounded by nearby neighbors, such as Naples Airport in Florida and Santa Monica Airport in Southern California.
A nationwide effort to “de-conflict” airspace in major metropolitan areas using existing technology and procedures is progressing, with studies completed at the first two of several designated sites.
While the LightSquared broadband wireless network’s potential to disrupt GPS signals has been widely publicized, a lesser known problem is the possibility of the system’s high-power transmitters interfering with satcom.
Electronic flight bags and newer devices like the Apple iPad and Android-based tablets are part of what is driving Jeppesen to more electronic distribution of its charting products, but that is just the tip of the iceberg.
Imagine the fun if every pilot’s understanding of where London Stansted Airport actually sits on the earth’s surface were a little different. Some might think it was in London proper, others in Essex, and a few more might be willing just to take their chances. When a passenger asked to be flown there, no one could really guarantee everyone would end up in the same place.
While the LightSquared broadband wireless network’s potential to disrupt GPS signals has been widely publicized, a lesser known problem is the potential of the system’s high-power transmitters to interfere with satcom.
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.
At press time, the first of three monthly reports of the technical arguments between experts from LightSquared and the GPS community over GPS jamming was about to be issued.
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.
