基于北斗的地基增强系统飞行试验性能

Performance of GBAS Flight Test Based on Beidou

地基增强系统(GBAS)以其全天候、减少飞行成本、提高机场吞吐量等优点,被视为下一代民航飞机主要的进近和着陆引导方式。在详细分析国内外基于GPS的GBAS系统相关资料的基础上,构建了基于北斗的GBAS系统,并在黑龙江鸡西市鸡西机场(JXA)进行了基于北斗GBAS的飞行实验。通过对基于BD与GPS的地基增强系统监测数据及保护级数据处理与对比分析,实验结果初步表明北斗卫星可以代替GPS作为中国下一代的GBAS导航源,并且本系统计算的完好性数据能够满足RTCA(航空无线电技术委员会)规范中对CATI类进近要求的定义。

Ground-based augmentation system （GBAS） is regarded as the main approach of the next generation of civil aviation aircraft, with the advantages of all weather, reducing the cost of flight and improving the throughput of the airport. Based on the analysis of the domestic and foreign related information GBAS system based on GPS, and build a GBAS based on Beidou.GBAS flight experiments based on Beidou satellite were carried out at JiXi Airport （JXA） in Heilongjiang Province .Through processing and comparative analysis on monitoring data and the protection level data of ground-based augmentation system based on BD and GPS,preliminary experimental results show that the Beidou satellite can replace GPS as Chinese next generation GBAS navigation source, and integrity data calculated by this system can meet the definition of RTCA （Aviation Radio Technical Commission） standard for CATI class precision approach.
