| Abstract: | A satellite attitude determination algorithm based on predigest error correction with star-sensor/ gyro is proposed to solve the problem of typical satellite attitude determination algorithm operation complexity. By predigest correcting the angular velocity of gyro, the states variables and complexity of filter are reduced. Simulation resvlts indicate that the proposed algorithm provides effective performance in the com- putational complexity and instantaneity when it performances as the same as the typical algorithm in attitude determination precision. |
