| 摘 要： | 随着天线定位机构运动日趋复杂以及对定位机构任务要求的不断提高,提高指向精度已成为星载天线机构能力提升的核心。综合考虑卫星姿态控制误差、展开机构误差、双轴驱动机构误差和反射面误差等因素,利用齐次变换矩阵得到天线指向运动学误差等式,从而得到天线指向精度分析的一般方法。以某星载点波束定位机构为例,对各误差源的影响进行了分析,...

| Abstract: | With the increase of the complexity of the antenna oriented mechanism and the higher requirement of mission,the improvement of the pointing accuracy has been the core of the capability improvement for satellitic antenna.With a comprehensive consideration of the errors of satellite attitude control,the errors of deployment mechanism,the errors of two-axis drive mechanism and the errors of the reflector,the transformation matrix are used to get the kinematic error equations of antenna pointing.Thus a common m... |
