摘要
GBAS在通过差分定位提高卫星导航精度的基础上,增加了一系列完好性处理算法,使机场覆盖空域范围内的配置相应机载设备的飞机获得到达I类精密进近(CAT-I)甚至更高标准的精密进近、着陆引导服务。GBAS在建设规划阶段,站址评估是确定运行GBAS性能的重要手段。主要介绍了GBAS系统的系统组成、工作原理,重点介绍了GBAS站址评估方法,并以某机场实测数据为例进行了GBAS站址评估,为后续GBAS投入应用提供了技术基础。
Based on the improvement of satellite navigation accuracy through differential positioning, GBAS adds a series of integrity processing algorithms to enable aircraft equipped with corresponding airborne equipment within the airspace covered by the airport to obtain precision approach and landing guidance services of CAT-I or even higher standards. In the construction planning stage of GBAS, site assessment is an important method to determine the performance of GBAS. The system composition and working principle of GBAS are introduced, focuses on the GBAS site assessment method, and GBAS site assessment with an airport actual measurement data is conducted as an example, which provides a technical basis for the subsequent application of GBAS.
