| 摘 要： | APVI/II是依靠卫星定位系统提供导航引导的飞行程序,不依靠地面导航设备就可将飞机精确地引导到跑道。国外依赖美国的GPS系统建立广域增强系统,从而实现APVI/II程序的大规模应用。中国有自主研发的北斗二代卫星导航系统,但当前北斗系统的垂直导航精度达不到APVI/II程序要求,可通过与气压高度融合,提高北斗垂直定位精度,以尽快实现APVI/II在中国的运行。在2020年北斗系统组网完成覆盖全球后,在其GEO卫星上添加星基增强信号,则可以使APVI/II应用得以广泛地实施。本文对北斗二代/气压高度组合导航的算法和程序安全性进行分析,论证现阶段中国使用北斗系统实施APVI/II飞行程序应用的可行性。

| Abstract: | APVI/II flight procedure is to rely on a satellite positioning system to provide navigation guidance instead of relying on the ground navigation aids. China has built its own Beidou II satellite navigation system, but the current vertical navigation accuracy has not reached the requirements for APVI/II procedure. Therefore, integrating the Beidou II satellite positioning and barometric altitude improves the Beidou II vertical altitude accuracy to satisfy APVI/II operation requirement. Global networking construction of Beidou system will be completed in 2020. Its GEO satellite sends satellite-based enhancement signal, which enables wide application of APVI/II. This paper analyzes the algorithm and safety of the flight procedure based on combined navigation of Beidou II/barometric altitude, demonstrating the feasibility of application of Beidou II system in APVI/II flight procedure in China. |
