Over the past ten years, since the MERIT project began in 1980, great changes have taken place and significant advances made in the area of Earth Rotation and Coordinate Reference Frames. Symposium 105, held at the 125th Anniversary Meeting of the International Association of Geodesy, August 1989, was devoted to this subject. Major improvements in techniques, such as VLBI and laser ranging, have been accompanied by corresponding improvements in data-processing procedures and theories of relevant phenomena. The papers included in this volume provide both a comprehensive record of past discoveries and a sound basis for further advances. Section headings are as follows: - Earth Rotation: Determination and Prediction - Earth Rotation: Interpretation - Reference Frames

This book on reference systems is the first comprehensive review of the problem of celestial and terrestrial reference systems and frames. Over 20 years, the importance of this problem emerged slowly as the accuracy of new observational techniques improved. The topic has already been approached in several symposia such as Stresa (1967), Morioka (1971), Perth (1973), Columbus (1975, 1978 and 1985), Kiev (1977) and San Fernando (1978). Two IAU colloquia held in Turin (1974) and in Warsaw (1980) were exclusively devoted to discuss reference systems. During this time, the problem of terrestrial and celestial reference systems has been discussed also in many astronomical and geodetic symposia, but always among other topics. Thus, a review devoted solely to the definition and practical realization of such systems was needed. It is hoped that this book, containing modern comprehensive reviews of important facets of this problem will contribute not only to a better and wider understanding of the mathematics and the physics that are behind the concepts and the realizations, but also to future development in a field that can only expand with the rapidly increasing accuracy of geodetic and astronomical observations. We are pleased to thank all the authors of the book who have enthusiastically agreed to contribute to the book in their field of competence and have gracefully accepted guidance from the editors in the definition of the subject and of the interfaces with other chapters. We thank Prof. Y.

This accessible reference presents the evolution of concepts of time and methods of time keeping, for historians, scientists, engineers, and educators. The second edition has been updated throughout to describe twentieth- and twenty-first-century advances, progress in devices, time and cosmology, the redefinition of SI units, and the future of UTC.

Reference systems and frames are of primary importance for many Earth science applications, satellite navigation as well as for practical applications in geo-information. A precisely defined reference frame is needed for the quantification of, e.g. Earth rotation and its gravity field, global and regional sea level variation, tectonic motion and deformation, post-glacial rebound, geocenter motion, large scale deformation due to Earthquakes, local subsidence and other ruptures and crustal dislocations. All of these important scientific applications fundamentally depend on a truly global reference system that only space geodesy can realize. This volume details the proceedigns of the IAG Symposium REFAG2010 (Marne la Vallée, France, October 4-8, 2010) The primary scope of REFAG2010 was to address today’s achievements on theoretical concepts of reference systems and their practical implementations by individual space geodetic techniques and their combinations, underlying limiting factors, systematic errors and novel approaches for future improvements.

The theory of precession and nutation deals with the motion of the Earth's principal axes of inertia relative to the system of axes fixed in space. Relative positions of these systems cannot be derived directly from the observation since this is capable of giving only the position of the zenith of the observatory among the stars. Thus the intermediate system of the moving equator was introduced. If the coordinates of the stars are given in this system the positions of the zenith will be obtained in the same system. A rotating frame of reference fixed to the Earth may be constructed by attaching its axes to the zeniths of several selected observatories. The equatorial plane of the system passes so that its angular distances from the zeniths are always as near as possible to some adopted constants.
