Abstract

To research the holistic and regional motions of the Earth and to detect the motion mechanism of each Earth layer, the terrestrial reference frame with a high accuracy is needed. Hereby the developments and current status of the International Terrestrial Reference Frame (ITRF) are briefly reviewed. Current achievements, unsolved questions and limitations are analyzed, and some goals and suggestions of the ITRF in the future are particularly proposed.
