Analysis of the factors influencing the attitude determination accuracy based on orthogonal experiment

Attitude determination is an important component of spacecraft control. Gyro and star sensor as sensors play a vital role in the attitude determination system and the error of them, such as misalignment, bias and noise, is one of the factors that influence the accuracy of attitude determination. In order to analyze the influence of these errors to attitude determination accuracy, orthogonal experiment method is effectively used. According to the results of a series of simulations, the conclusion that in sensor errors star sensor misalignments and noises are the main factors influencing the attitude determination accuracy is drawn.
