Feasibility Demonstration of Terrestrial RNP with LDACS

In this paper we discuss the first results from a set of flight experiments. The objective was to show that terrestrial ranging can support aviation services with sufficient accuracy for non-precision approach. The experimental setup is based on using LDACS signals to provide pseudorange measurements. The data analysis reveals that the position solutions are compliant with RNP 1 standards. We also propose the feasibility of RNP 0.3 using LDACS as terrestrial ranging.
