GBAS功能需求的地面测试研究

星基导航技术在民航界得到了越来越多的应用和推广,GNSS地基增强系统GBAS作为星基导航提供精密进近必不可少的手段之一受到了广泛关注。和陆基导航设备一样,GBAS在正式使用和对外开放之前都需要进行测试和验证,本文阐述了GBAS的基本组成及工作原理,根据国际民航组织的要求,对GBAS在投入使用前需要进行的功能测试进行了概述,并对测量的参数进行了详细的分析说明。给出了GBAS地面功能测试的方法,详细介绍了GBAS精度的测量,为国内运行GBAS提供了技术参考。

Research on Ground Testing of GBAS Functional Requirement

Satellite-based navigation technology has been applied and popularized more and more in the civil aviation industry. GBAS, which is the enhancement of Global Navigation Satellite System (GNSS), as one of the indispensable means for Satellite-based Radio Navigation System providing precision approach have been widely concerned. As with the Ground-based Radio Navigation System, GBAS needs to be tested and validated before use and opening. The composition and working principle of GBAS are presented. According to the requirements of the international civil aviation organization, the functional testing of GBAS before use is reviewed, and the parameters of the measurement are analyzed in detail. The GBAS ground testing methods of functional requirement are given and the accuracy of GBAS is introduced in detail, and the technical reference for the operation of GBAS in the domestic is provided.
