Federal Radionavigation Plan -- A Perilous and Expensive Airway for Civil Aviation?

摘要

The Federal Radionavigation Plan states that all present navigation and landing guidance facilities will be retired in 2005 to 2010, and full dependence for these functions will be placed on augmented GPS. Once this is implemented, civil aviation will be totally vulnerable to terrorist jamming of the GPS signals over wide earth areas with potentially widespread disruption of air traffic and possible disasters. It has also become apparent that the use of GPS/GNSS is complex and expensive for the required civil aviation functions. It is clear that a different system form is needed for civil aviation, a redundant satellite/ground based system that will prevent it from being a jamming target while providing ATC surveillance, navigation, collision warning/avoidance, high-speed data link, Cat. I landing guidance and voice com-munications globally, plus precision Cat.III guidance in the terminal areas as needed. Such a system will be described.
