大口径天线精确对星算法改进
Improvement of precision alignment algorithm for large diameter antenna
摘要
Abstract
Based on the attitude information provided by a large diameter antenna,the calculation model of the satellite coordinates of the existing antenna is improved.Through the space rotation coordinate system method and the plane geometry triangulation method,the star angle in the geographic coordinate system is deduced.According to the problem that the star angle of the large diameter antenna is higher,the original model is improved,and a more accurate angle calculation model is given.Due to the unstable factors,the calculation method for the star angle in the carrier coordinate system is proposed.The simulation results show that the model can improve the performance of large diameter antenna.关键词
