基于BDS的ADS-B报文生成系统

目前国际民航组织（ICAO）和美国航空无线电技术委员会（RTCA）有关广播式自动相关监视（ADS-B）标准中的报文数据源均规定来自全球定位系统（GPS），而中国自主建设的“北斗”卫星导航系统（BDS）作为ADS-B数据源是必然趋势。设计了基于BDS的ADS-B报文生成系统的总体架构，利用BDS接收机接收的真实数据仿真生成了ADS-B的6种报文，并以空中位置报文的生成为例，详细阐述了报文产生涉及的关键技术以及报文的生成过程。通过运行集成后的ADS-B报文生成系统以及对所产生的6种报文的仿真验证，证明该系统总体设计思路合理，运行结果正确，可为基于BDS的ADS-B相关技术研究提供稳定可靠的ADS-B报文源。

An ADS-B message generation system based on BDS

Currently,the message data sources in the Automatic Dependent Surveillance-Broadcast(ADS-B) standards recommended by the International Civil Aviation Organization(ICAO) and American Radio Technical Commission for Aeronautics(RTCA) are all stipulated to originate from the Global Positioning System(GPS),while it is an inevitable trend that the Beidou Satellite Navigation System(BDS) self-constructed by China provides the BDS data for ADS-B.The overall architecture of ADS-B message generation system based on BDS is designed,and six kinds of ADS-B messages are simulated and generated using the real data received by BDS receiver.The key technologies related to the message generation and the process of the message generation are illustrated by the example of generation of the airborne position message.By the operation of the integrated ADS-B message generation system and the simulated verification of generated six kinds of messages,it is proved that the idea of general design is reasonable and the operation results are correct,and the stable and reliable ADS-B message source can be provided for the research related to ADS-B technologies based on BDS.
