摘要
借鉴数值分析的思想,在大地椭球模型的基础上采用IERS2010规范,结合成熟的基本天文标准(SOFA)程序库,在C++环境下设计一种基于GCRS-ITRS变换关系的星下点计算方法,以满足其实时性及精确度的要求。
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.
