A Modular Approach to Integrity for APNT

Abstract:	The low availability of terrestrial sources is a key challenge in providing alternative position, navigation and timing (APNT) services with integrity to civil aviation. This paper proposes a new way of facing this challenge by combining measurements from diverse systems. The proposal includes two different ways of deriving integrity from such a combination. One method is based on combining position solutions from different systems, the other is based on combining measurements from different systems into a single estimation process. We compute the expected performance of each method over Germany and study their potential to provide Required Navigation Performance (RNP) services.
