由于当前精密星历所对应解算的ITRF框架坐标为ITRF2008参考框架,而在1∶10 000基础测绘生产项目要求提供CGCS2000坐标系成果,论述了ITRF2008到CGCS2000间的框架转换的方法及转换后精度分析,并重点分析了转换的关键性问题。 更多还原

【Abstract】 Based ITRF2008 reference frame on ITRF frame coordinate which is related to present precise ephemeris,and the achievement of CGCS2000 coordinate axis which is required in the basic mapping producing project about scale of one to a ten thousand, the thesis mainly discussed the conversion method of frame from ITRF2008 to CGCS2000 and the precision analysis after conversion. It also mainly analysed some key problems about transformation. 更多还原
