卫星导航转台天线旋转关节时延特性分析

内容简介：为确保卫星导航系统星地时间同步精度，要求转台天线旋转关节具有良好的时延特性。通过对非接触式、接触式和电缆替代式三种旋转关节时延特性的分析和比较，结合典型关节的时延测试试验，结果表明：电缆替代式旋转关节具有更好的时延特性。

Abstract：In order to keep the precision of time synchronization between satellite and ground for the satellite navigation system, the time-delay characteristic of antenna rotatory joint is required to be well. Three types of rotatory joint including of non-osculating, osculating and cable substituted are analyzed with the representative time-delay test. The result shows that the fashion of cable substituted has better character.
