摘要: 针对自动广播相关监视(ADS-B)数据链存中GPS信号容易受到干扰的情况,提出了一种自动监测和粗定位方法来确定GPS信号干扰源。该技术处理方法在不改变现有ADS-B系统的基础上,只是对系统软件功能进行扩展,利用ADS-B地面站接收的目标数据,实时跟踪每个目标的运动轨迹,制定跟踪规则和算法,开展GPS信号干扰分析,准确获取GPS信号丢失和恢复的时间、经纬度、高度等数据,并与飞机的飞行轨迹进行对比分析,同时将分析数据展现在电子地图上,通过飞行大数据分析降低GPS信号干扰排查成本,提升人工排查GPS信号干扰源的效率,减少民航飞行安全隐患。

Abstract: In this paper, an automatic monitoring and coarse localization method is proposed to identify GPS signal interference sources for the vulnerability of GPS signals in the automatic dependent surveillance-broadcast(ADS-B) data chain.The proposed technique works without changing the existing ADS-B system, just to extend the system software capabilities. Using the target data received by the ADS-B ground station, the movement trajectory of each target is tracked in real-time, developing tracking rules and algorithms,interference analysis of GPS signals is carried out. The time, latitude, longitude and height of GPS signal loss and recovery are accurately acquired, and compared with the flight trajectory of the aircraft, and the analytical data will be displayed on the electronic map. The proposed technical mothed reduces the cost of GPS signal interference detection through flight big data analysis, improves the efficiency of manual investigation of GPS signal interference sources, and reduces the potential civil aviation flight safety risks.

交通運輸業(yè)的繁榮是現(xiàn)代社會文明與進步的標(biāo)志之一,但其持續(xù)性高速發(fā)展的背后也逐漸暴露出一些問題。如當(dāng)前民航機場及其相關(guān)航線所表現(xiàn)出的擁擠情況正在日益加劇,繼而導(dǎo)致航班準(zhǔn)點率下降愈發(fā)嚴(yán)重,不僅顯著增加了航班調(diào)度工作量,同時也會造成一定程度的經(jīng)濟損失。為了較好地緩解這一問題,除了通過某些行政手段與管制制度加強空域與航線的管理與規(guī)劃外,另外一個非常重要的途徑就是通過采用更為先進的機載設(shè)備,配套部署并建設(shè)更為完善的“空-空”與“地-空”數(shù)據(jù)鏈以及將相關(guān)地面設(shè)備進行升級等,繼而建立起一個更高效與立體化的空管監(jiān)視、運行與管制的設(shè)備體系。廣播式自動相關(guān)監(jiān)視系統(tǒng)(ADS-B)正是在這樣的需求前提下應(yīng)運而生的[1],且已在不斷的試驗性應(yīng)用中逐步得到發(fā)展和成熟。
