In order to solve the problem of high error rate in traditional spacecraft attitude measurement method,a high precision attitude measurement calibration method based on precision satellite sensor is proposed.The precision satellite sensors used are designed first and will be installed in appropriate positions without affecting the operation of the spacecraft.Through the establishment of motion system,the parameters of coordinate conversion and attitude parameters of the three steps to get the spacecraft motion model,under the model analysis of the basic motion of spacecraft attitude,using high precision star sensor identification and selection of spacecraft under arbitrary three star,finally integrated positioning of the star and the movement of spacecraft attitude,determine the spacecraft attitude measuring results from different angles,in order to improve the accuracy of the spacecraft attitude measuring results of calibration process.Through the analysis of simulation experiment,the conclusion is drawn that compared with the traditional measurement method,the average error rate of the spacecraft high-precision attitude measurement calibration method based on precision star sensor reduces by 6.0%.
The design and implementation of a high-precision attitude measurement calibration method for spacecraft based on precision star sensors effectively reduce the error of spacecraft attitude measurement results and obtain more accurate measurement results. The application of design methods can provide high-precision data for the precise control of spacecraft operation and operation, thus having high application value.
