无人机机载天线单轴稳定平台设计与实现

Design and Implementation of Antenna Stable Platform of Pilotless Helicopter

针对无人机机载垂直极化天线电轴受飞机姿态影响的问题 ,介绍一种天线稳定平台的设计方法。文中讨论其机械结构设计原理、选择伺服机构电机时的力矩计算方法。

A design scheme of antenna stable platform is introduced.The stable platform is uesd to eliminate the influence of helicopter attitude on the vertical polarized antenna.Without the stable platform,the high attitude of pilotless helicopter is big enough to make polarization direction of airborne antenna unparallel to that of the base antanna and decrease received power.The design of mechanism,problems in servo selection and system implementation are presented.
