GBAS数据回放系统技术研究及实现

Research and Implementation of GBAS Data Playback System

随着全球导航卫星系统(GNSS)地基增强系统(GBAS)在机场的长期使用,能够实现回溯历史数据、模拟卫星系统故障、进行GBAS运行性能的验证分析和问题定位,就显得很有必要,而如何使用GBAS系统记录的历史数据是实现以上功能的先决条件。通过研究实现了一套针对于GBAS原始数据的数据回放系统,方便了GBAS系统后期历史场景复现、问题定位和系统的性能验证和分析。

With the long-term use of the Global Navigation Satellite System(GNSS)Ground Based Augmentation System(GBAS) at the airport,it is necessary to be able to track historical data,simulate satellite system failures,verify and analyze GBAS operational performance and locate problems.How to use the historical data recorded by the GBAS system is a prerequisite for achieving the above functions.A set of data playback system for GBAS original data is implemented,which is convenient for the historical scene recurrence,problem location and performance verification and analysis of GBAS system in the later period.
