一种无人机定向天线稳定跟踪系统

Research of Stable Tracking System for the Directional Antenna of UAV

天线正确稳定地跟踪无人机飞行方向是保障无人机安全有效工作的关键问题;设计了一种无人机天线跟踪系统方案,描述了其工作原理,并讨论了GPS位置计算天线方向、跟踪系统的控制方法和控制精度;整个系统设计方案简洁,运行成本低,可适用于不同地面控制站使用;提出了一套基于单片机处理器的定向天线自动稳定跟踪系统研制方案,为中小型无人机飞行数据链路的畅通和安全提供保障作用。

The key problem to keep UAV work safely and efficiently is that the directional antenna can track the flight direction of UAV steadily. This paper proposes a preliminary design scheme of antenna sta- ble tracking system, describes its operational principle, and then discusses antenna direction according to GPS positions, control method and accuracy of the tracking system. The structure of the system is simple and inexpensive, and it is applied for different ground control stations.
