Abstract
In order to observe the photodynamic characteristics of periodic variable stars, a periodic variable star ground observation system is designed with high frequency and high precision star sensor. The high precision star sensor is used to determine the attitude information of the system, and the NFOV star sensor is used to detect atmospheric changes and other environmental factors to track the variable stars accurately. The accuracy measurement matrix and the pointing vector of the star sensor are obtained from the attitude matrix and the accuracy measurement transformation matrix of the star sensor. Finally, the pointing and rolling accuracy of the star sensor are obtained by the accuracy evaluation standard. The system is validated for the observation of periodic variable stars and high dynamic detection, which provides the observation basis for the application of periodic variable stars.
