摘要: 偏差是陆基增强系统(GBAS, ground-based augmentation system)机载接收机适航论证的重要性能指标。 根据美国航空无线电委员会(RTCA,Radio Technical Commission for Aeronautics)颁布的 DO-253D 中对GBAS 机载接收机偏差输出的要求,分析研究了偏差的来源,给出了完整的偏差解算过程,并推导出偏差阈值。 随后,分别在静态和动态场景下对基于北斗的 GBAS 机载接收机偏差输出进行仿真分析。 结果表明,基于北 斗的 GBAS 机载接收机偏差输出能够满足精密进近引导输出的要求, 可为中国 GBAS 机载接收机适航标准的制定提供理论支持。

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
