Abstract

The distance measuring equipment (DME), a radio-navigation aid, can be used to provide a redundant navigation system alongside GPS/WAAS (global positioning system/wide area augmentation system) during a phase-out period. Specifically, a system that fuses a low-end DME receiver with low-cost dead-reckoning sensors provides an affordable area navigation capability for general aviation users. The justification for choosing DME over other ground-based navigational aids is that the back-up system allows the reduction of the number of operational radio-navigation aids required while providing adequate coverage for navigation during the transition to a sole-means GPS national airspace system.
