Abstract

Abstract: Deviation is an important performance indicator for airworthiness demonstration of GBAS (ground-based augmentation system) airborne receiver. According to the requirements of deviation outputs for GBAS airborne receiver DO-253D issued by RTCA (Radio Technical Commission for Aeronautics), the source of deviation is analyzed, the complete solution process of deviation is given, and the threshold of deviation is derived. Accordingly, the deviation outputs of Beidou-based GBAS airborne receiver are simulated and analyzed in static and dynamic scenarios. Simulation results show that the deviation outputs of Beidou-based GBAS receiver can meet the requirements of precision approach guidance outputs, which provides theoretical support for the formulation of GBAS airborne receiver airworthiness standards in China.

Key words: Beidou, ground-based augmentation system (GBAS), airborne receiver, deviation, final approach segment
