基于嵌入式系统的 ADS-B 接收机软件设计和关键技术分析

摘要

Automatic Dependent Surveillance-Broadcast is a new ATC (air traffic control) technology for surveillance, information transfer and navigation. It is based on Mode-S air-to-ground and air-to-air data links. This paper proposes a new design of ADS-B receiver based on Vxworks embedded operating system. Key techniques such as adjacent plane data managing, gray decoding and position information processing are investigated in detail. Associated software implementation issues are also investigated.%　　广播式自动相关监视(ADS-B)是基于 S 模式空-地、空-空数据链完成监视、信息传递和导航的一种空中交通管制(ATC)新技术。本文提出了基于 Vxworks 嵌人式操作系统的 ADS-B 接收机核心软件设计，论述了系统实现所需的邻机数据管理、格雷码解码以及位置信息处理等关键技术以及软件实现方法
