| 针对单个广播式自动相关监视（Automatic Dependent Surveillance-Broadcast，ADS-B）发射机传输距离受限、多地面站组网复杂以及成本较高等问题，在分析ADS-B报文编码与解码算法的基础上，探讨了基于无线网络传输的ADS-B报文信息技术，并设计了基于“北斗”卫星导航（BeiDou Satellite Navigation System，BDS）/嵌入式控制器以及无线网络的便携式监视终端系统。利用实测ADS-B数据联合搭建的监视中心对算法和系统进行测试，结果表明数据传输稳定，实现了低空空域通用航空飞机ADS-B态势信息的网络传输功能，丰富了监视信息的链路传输方式，为低空通航飞行器安全飞行和全面监视提供了新的方法。 |

| Abstract: |
| In order to solve the problems of limited transmission distance of single automatic dependent surveillance-broadcast(ADS-B)transmitter,complex multi-ground stations networking and high cost,the ADS-B message encoding and decoding algorithm is analyzed,the ADS-B message information technology based on wireless network is discussed,and a portable monitoring terminal system is designed based on BeiDou Satellite Navigation System（BDS）/embedded controller and wireless network.The algorithm and system are tested by the monitoring center built with the measured ADS-B data.The results show that the data transmission is stable,and the network transmission function of general aviation aircraft situation information is realized in low-altitude airspace.The results of this research enrich the transmission link monitoring information and provide a new method for low altitude navigation of aircraft flight safety and overall monitoring. |
