Abstract Taking the data of China geoid datum in consecutive days,as an example,the latest International Terrestrial Reference Frame(ITRF2008) was used to analyzed the difference between ITRF2008 ,ITRF2005 and CGCS2000. It is valuble maintaince to China geoid datum. It is concluded that the ITRF2008 more precise than the previous ITRF models, but there are some differences, which is related with observation stations, plate, the strategy for data solving and other factors. The nonuniforming and complexity of the earth plate movements cause the CGCS2000’s changes which should be dynamicly maintained.In the same time,the transformation scheme between CGCS2000 and ITRF2008 is preliminarily described.
Key words ：
ITRF
ITRFS transformation
CGCS2000
