Abstract There are four parts mainly involved: 1)development and estimation on the International Terrestrial Reference Frame (ITRF), the main characteristics of the most new ITRF2005; 2)definition, construction and maintenance of a local geodetic reference coordinate frame, present situation and development of the local geodetic reference coordinate frame in Europe, America and north America; 3)the modernization of the vertical datum, the progress in the establishment of a modern vertical datum in United States of America and Europe, and the way how to establish a global vertical datum; 4)some special problems should be concerned in the construction of a geodetic reference coordinate frame, for example, the contribution of VLBI and SLR, the way to reduce the influence of the periodical variation of the frame points on the precise positioning, and the improvement suggestion for the computation of zero tide system.
