摘要
可用性是衡量地基增强系统(GBAS)的重要指标,本文针对GBAS的应用需求和多种着陆系统相关标准,结合GBAS卫星完好性的计算方法,对基于COMPASS的GBAS的CATI类精密进近的可用性进行了仿真和分析,为GBAS在多种着陆标准下的工程应用提供参考。
Availability is the important performance index for Ground Based Augmentation System （GBAS）. According to the application requirements of GBAS and several standards for approaching and landing with satellite navigation technology, the availability of CAT I precision approach based on COMPASS system is simulates and analyses which combined with the GBAS integrity processing method. Finally, the support for GBAS application under multiple standards is provided in this paper.
