用IERS公布的14个ITRF转换参数(7个转换参数及7个转换参数的速率),把不同ITRF下IGS站的坐标相互转换,将IGS站的坐标和自编程序计算结果进行对比,坐标差达到了厘米级的精度.
用IERS公佈的14箇ITRF轉換參數(7箇轉換參數及7箇轉換參數的速率),把不同ITRF下IGS站的坐標相互轉換,將IGS站的坐標和自編程序計算結果進行對比,坐標差達到瞭釐米級的精度.

The problems that how the coordinates of IGS under different ITRF can be transformed into other ITRF by using 14 transformation parameters announced by IERS (7 transformation parameters and their rates) are studied. Furthermore, coordinates of IGS are compared with those computed and the results show that the differences of coordinates are at centimeter level.
