摘要
卫星导航地基增强系统是一种旨在代替传统仪表着陆系统的终端区进近引导设施,安装一套设备即可为机场的多条跑道提供进近引导服务。对于一些大型机场,通常会在地面安装两个VDB发射台以增大其覆盖范围,但是传统的飞行校验不能区分信号是哪个台站发出的,因此在多个台站的情况下无法评估各台站的覆盖性能。针对这一问题,提出了一种基于EVSF1000设备的多时隙数据分析方法,通过对VDB信号的8个时隙数据进行解析和数据处理,从而实现在一次飞行中完成对两个地面台站VDB信号和数据的评估,从而满足了双VDB台站配置系统的飞行校验需求。所提出的方法在天津滨海机场的GBAS校验飞行测试中得到验证,可成功实现对双VDB台站的检查评估。
Ground based augmentation system(GBAS)is a terminal area approach guidance facility designed to replace the traditional instrument landing system(ILS).One set of equipment can provide approach guidance service for multiple runways of the airport.For some large airports,two VDB transmitters are usually installed on the ground to increase system coverage.However,traditional flight inspection cannot identify which station emits the signal from the reception,which causes failure of station coverage evaluation.This paper proposes a multiple slot data analysis method based on EVSF1000 unit,which can analyze and evaluate the VDB signals of multiple ground stations in one flight by decoding and parsing data from 8 VDB time slots,to achieve the flight verification requirements of GBAS system with dual VDB stations.The method is verified in an GBAS inspection flight which completed the inspection of dual VDB stations installed in Tianjin Binhai Airport.
