| 摘 要： | 简要介绍了WGS84坐标系和ITRF框架,给出了不同ITRF框架间的坐标转换流程,并利用实例对WGS84与ITRF框架间的转换关系进行了验证分析。结果表明,ITRF2008与WGS84坐标基本一致,但由于ITRF框架的站速度对站坐标的影响与时间成正相关,当需要采用ITRF框架时,应选用最新的国际地球参考框架。

| Abstract: | In this paper,we briefly introduced the coordinate system of WGS84 and ITRF frames,gave the coordinate conversion process between different ITRF frames,and verified and analyzed the conversion relationship between WGS84 and ITRF frames by an example.The results show that ITRF2008 and WGS84 coordinates are basically the same,but since the influence of station speed of ITRF frame on station coordinates is positively correlated with time,the latest international earth reference frame should be used when the ITRF frame is needed. |
