RESEARCH ON COORDINATE TRANSFORMATION BETWEEN GCRS AND ITRS
GCRS与ITRS之间的坐标转换研究

The coordinate transformation between the geocentric celestial reference system(GCRS) and the international terrestrial reference system(ITRS) is one of the main questions for studying in astronomy / geodesy.In the coordinate conversion process based on Equinox,deduced the coordinate expression of instantaneous celestial intermediate pole(CIP) in GCRS is the basis for coordinate transformation based on non-rotating origin(NRO).According to the choice of Euler angles,the concepts of the celestial pole offset...
