摘要
在卫星应急恢复过程中,为了控制太阳电池阵的对日方位,需要确定太阳电池阵相对于卫星本体的转动角度。为此,提出一种用于卫星应急恢复的太阳电池阵转角估计方法。首先,基于卫星本体坐标系和太阳电池阵坐标系的关系以及卫星的姿态运动学方程,给出了太阳电池阵转角的解析解。在太阳电池阵转角解析解的基础上,进一步提出一种基于卡尔曼滤波的估计方法,来抑制太阳敏感器测量噪声的影响、提高转角估计的准确性。通过数值仿真和某实际在轨卫星的遥测数据实验验证了所提方法的有效性和实用性。
In the process of satellite emergency recovery,it is necessary to determine the rotation angle of solar cell array relative to satellite body to control its sun orientation.For this purpose,a solar cell array rotation angle estimation method for satellite emergency recovery is proposed.Firstly,the analytical solution of solar cell array rotation angle is given by using the relationship between satellite body coordinate frame and solar cell array coordinate frame and the satellite attitude kinematics equation.Based on the determined analytical solution of solar cell array rotation angle,a Kalman filtering-based estimation approach is further proposed to attenuate the influence of measurement noises of sun sensor and improve the estimation accuracy of rotation angle.The effectiveness and validity of the proposed method are demonstrated by numerical simulations and the experiment on telemetry data of an on-orbit practical satellite.
