摘要
资源三号(ZY-3)卫星是一颗民用高分辨率立体测绘卫星.针对ZY-3卫星特点,对控制系统方案进行概述.通过星敏感器相对基准的标定以及星敏感器和陀螺联合滤波实现高精度姿态确定;通过设计结构滤波器和磁卸载力矩的前馈补偿实现三轴高稳定度控制;通过轨迹规划实现大角度侧摆机动.根据卫星在轨运行数据,给出相应指标实现情况,对姿态控制系统的方案和指标满足情况进行在轨验证.
Zi Yuan 3 （ZY-3） is the first civilian high resolution stereo mapping satellite in China. The at- titude control system of ZY-3 is introduced. By calibrating the relative reference of star sensor and apply- ing the star sensor and gyro integrated filter, the high accuracy of attitude determination is achieved. High stability of three-axis control is realized by adopting a structure filter and using the feedforward com- pensation of magnetic unloading torque. The large-angle roll maneuver is achieved by using trajectory planning. Based on on-orbit data of ZY-3 satellite, the implementation of specific indexes is proposed. Furthermore, the scheme of control system is tested on orbit.
