摘要:
Geodesy, geophysics, astronomy, and astrophysics are all exploiting the unprecedented progress in the accuracy of metric measurements made from space and the earth's surface. Measurements of polar motion and earth rotation, crustal deformation and displacement, satellite and planetarymotion, and the positions of stars and quasars are all being refined. These new measurements are providing information on plate tectonics and earth dynamics, the earth's variable rotation, the evolution of the moon and planets, the scale of the solar system and the universe, and the local space‐time metric. A common requirement of all these investigations is the necessity of a well‐defined coordinate system (or systems) to which all relevant observations, theories, and models can be referred and which can be used as a basis for discussion. In view of the widespreaduse and interdisciplinary implications of these observations, there is a need for the definition, practical realization, and international acceptance of a suitable coordinatesystem (or systems) to facilitate such work. The need, the scope of the issues, and the nontriviality of the problem is evidenced by the numerous specialized symposia organizedduring the past dozen years: Stressa [Markowitz and Guinot, 1968], Morioka [Melchior and Yumi, 1972; Yumi, 1971], Torun [Koaczek and Weiffenbach, 1974], Columbus [Mueller, 1975, 1978], Kiev [Federov et al, 1980], San Fernando [McCarthy and Pilkington, 1979], and recently, Warsaw [Gaposchkin and Ko/aczek, 1981]. The Warsaw meeting (September 8–12, 1980) is the subject of this r
