Abstract:In this paper, we use the theory of numerical analysis and design a method of ground track point calculation based on GCRS-ITRS transformation. Based on the earth ellipsoid model and the IERS2010 standard, combined with the mature basic library of Standards of Fundamental Astronomy (SOFA),under the enviroment of C++, the method can satisfy the requirements for real-time and accuracy.
