| 摘 要： | 提出了一种利用陀螺与星敏感器进行组合定姿的方案.为了避免状态及量测向量选取不当而造成的误差,首先采用四元数法对卫星的姿态进行描述;接着分析了陀螺与星敏感器系统的误差源,选取误差四元数及陀螺的系统误差作为组合系统的状态,获得了系统状态方程;同时采用星敏感器的量测作为系统量测,并利用新的数学变换构得到更为准确的量测方程;最... |

| Abstract: | an integrated attitude determination algorithm based on gyroscopes and star sensor is presented in this paper.First,satellite attitude is described with quaternion to avoid the error caused by incorrectly selecting state and measurement vector.Then the error sources of gyroscopes and star sensor are thoroughly analyzed and the quaternion and gyroscopes error are adopted as state variables,by which system state equations are well constructed.Measurement matrix is constructed by using measurements from star s... |
