| 摘 要： | 通过预测滤波方法研究了利用矢量观测确定无陀螺飞行姿态和角速度的方法。给出的观测滤波法在一定的二次型优化准则下，对飞行器姿态和名义姿态运动模型的等效角速度误差可同时进行实时估计，能够准确跟踪敏感器的测量，有效减小模型误差的影响，数值仿真结果验证了算法的优越性。

| Abstract: | Gyroless spacecraft attitude and rate determination from vector observations was studied using predictive filtering. Under a certain optimal quadratic criterion, the spacecraft attitude and the equivalent rate error of the nominal model of attitude motion were estimated simultaneously in real time. The filter can accurately track the sensor measurements and therefore alleviate the effect of model uncertainties effectively. Numerical simulations for the demonstration of its performance were presented. |
