Feasibility Demonstration of Terrestrial RNP with LDACS

Kurzfassung

While many existing systems are capable of supporting current and near-term plans in Alternative Position, Navigation, and Timing (APNT) services, it has become apparent that state-of-the-practice technologies will not support the most demanding Performance-Based Navigation (PBN) services. Specifically, to achieve the most demanding Required Navigation Performance (RNP) types, Distance Measuring Equipment (DME) will not be sufficient, so new methods and hardware are needed. The use of the L-Band Digital Aeronautical Communications System (LDACS) for navigation applications has long been proposed as a way of pushing the envelope on terrestrial RNP, in particular moving towards RNP 1 or RNP 0.3 types.
