This paper introduces the Mode N system concept – a terrestrial navigation system intended for aviation – developed by the air navigation service provider (ANSP) of Germany, Deutsche Flugsicherung. Proposed as a new system, Mode N is presented in the context of other alternative position, navigation, and timing (APNT) systems because it blends aspects of these systems together in its own design. This paper leverages that characteristic by identifying the similarities with other APNT systems and tailoring the large body of APNT work to evaluate Mode N and model the range accuracy for the Mode N signal. This range accuracy model is then used in a basic coverage assessment for Germany.
