| 摘 要： | 针对无陀螺或陀螺失效等情况下的卫星姿态确定问题,应用基于Unscented变换的Unscented滤波理论,提出了仅利用星敏感器矢量观测信息来确定无陀螺卫星姿态的Unscented卡尔曼滤波算法,并进行了数学仿真,仿真结果表明了所提出的UKF算法在无陀螺情况下对卫星姿态估计的有效性和可靠性。

| Abstract: | Satellite attitude determination algorithm only applying to vector observation from the star sensor,under both gyros-less and gyro-disable modes using unscented Kalman filter theory based on unscented transformation, is derived.The mathematical simulation is presented and the results indicate the availability and feasibility of the UKF algorithm for satellite attitude estimation under the gyro-less mode. |
