This book on space geodesy presents pioneering geometrical approaches in the modelling of satellite orbits and gravity field of the Earth, based on the gravity field missions CHAMP, GRACE and GOCE in the LEO orbit. Geometrical approach is also extended to precise positioning in space using multi-GNSS constellations and space geodesy techniques in the realization of the terrestrial and celestial reference frame of the Earth. This book addresses major new developments that were taking place in space geodesy in the last decade, namely the availability of GPS receivers onboard LEO satellites, the multitude of the new GNSS satellite navigation systems, the huge improvement in the accuracy of satellite clocks and the revolution in the determination of the Earth's gravity field with dedicated satellite missions.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 15. This monograph contains 34 communications presented at the Third International Symposium on the Use of Artificial Satellites for Geodesy in 1971, and 4 invited papers on subjects that complement the others and provide continuity. All contributions represent the most recent findings in the theoretical and applied fields of satellite geodesy, including new instrumentation (satellite sensors and ground equipment) of potential use in satellite geodesy. The two preceding symposiums were held at Washington, D.C., in 1962 and at Athens, Greece, in 1965. The Proceedings of the first were published by North-Holland Publishing Company, Amsterdam, in 1963, and the Proceedings of the second by the National Technical University, Athens, in 1967. The prime mover behind both was George Veis, and his continuing dedication to this subject was in large measure responsible for scheduling this third symposium.

Completely revised and updated edition. The book covers the entire field of satellite geodesy (status spring/\break summer 2002). Basic chapters on reference systems, time, signal propagation, and satellite orbits are updated. All currently important observation methods are included and also all newly launched satellites of interest to geodesy. Particular emphasis is given to the current status of the Global Positioning System (GPS), which covers now about one third of the book. A new chapter on Differential GPS and active GPS reference networks is included. The GPS modernization plans, GLONASS, the forthcoming European system GALILEO, modern developments in GPS data analysis, error modelling, precise real time methods and ambiguity resolution are dealt with in detail. New satellite laser ranging missions, new altimetry missions (e.g. TOPEX/Poseidon, ERS-1/2, GFO, JASON), and new and forthcoming gravity field missions (CHAMP, GRACE, GOCE) are also considered. The book serves as a textbook for advanced undergraduate and graduate students, as well as a reference for professionals and scientists in the field of engineering and geosciences such as geodesy, surveying, geo-information, navigation, geophysics and oceanography.

The book content corresponds to a course of the International Summer School of Theoretical Geodesy held every 4 years under the sponsorship of the International Association of Geodesy. This particular course, that was given at the International Centre for Theoretical Physics in Trieste, has been dedicated to the theory of satellite altimetry as a response to the increasing need of scientific work in this field due to important recent and forthcoming space mission. The course was conceived to supply a good theoretical basis in both disciplines, i.e. geodesy and oceanography, which are deeply involved in the analysis and in the use of the altimetric signal. The main items of interest are the physical theory of ocean circulation, the theory of tides and the ocean time-variability, from the point of view of oceanography and the orbit theory, with particular regard to the formation of the radial orbital error, the so-called cross over adjustment, the analysis of geodetic boundary value problems, the integrated determination of the gravity field and of the radial orbital error, from the point of view of geodesy. All these arguments are treated from the foundation by very-well experts of the various fields, to introduce the reader into the more difficult subjects on which advanced research is currently performed. The peculiarity of the book is in its interdisciplinarity as it can serve to both communities of oceanographers and geodesists to get acquainted with advanced aspects one of the other.

Celestial mechanics aims to predict the motion of every real object in outer space, no matter what causes changes in its orbit. The motion of most planets and natural satellites can be successfully described by conservative celestial mechanics and problems can be studied within the formalism of Hamiltonian mechanics. The few exceptions which experience significant non-gravitational effects call for only very small corrections to the purely gravitational theory. All satellites experience non-gravitational perturbations to their orbits. However, factors such as the relatively high area-to-mass ratio of spacecraft compared with that of even a tiny asteroid significantly increase the relative effect of non-gravitational to gravitational forces on the orbits of artificial satellites. When the orbital tracking is carried out by very accurate techniques, the need arises to model, or at least to estimate, the effects of phenomena such as radiation pressure from solar light and from Earthshine or drag caused by neutral and charged particles. This book presents the basic ideas of the physics of the main non-gravitational perturbations and the mathematics of the methods required to compute their orbital effects. The authors convey to the reader the relevance of the different problems that need to be solved to achieve a given level of accuracy in the orbit determination and in the recovery of geophysically significant parameters. The book will enable readers to assess for themselves the possible geodetic uses of given space missions, or maybe to propose a new one, or to propose a combined geodetic use for a mission envisaged for other purposes. The Authors Andrea Milani is a mathematician, Anna Maria Nobili ad Paolo Farinella are physicists. They began working together in celestial mechanics and satellite geodesy in 1978, when they formed, with others, the Space Mechanics Group now based at the Department of Mathematics of the University of Pisa, Italy. By travelling to many research centres in Europe and in the USA, and by presenting several proposals for space-based experiments to the European Space Agency and to the Italian Space Program, they have learned how to assess the difficulty of an orbit determination and how often the problem is due to poor modelling of very-subtle non-gravitational effects, In this book they try to make their know-how available to others, as well as teaching some basic tools of celestial mechanics on the basis of their experience in basic research. A Milani and A M Nobili also work on the stability of the solar system, P Farinella also studies the dynamics and physics of the asteriod belt.

The purpose of this reference and handbook is to describe and to derive the analytic solutionsoftheequationsofsatellitemotionperturbedbyextraterrestrialandgeo- tential disturbances of the second order. The equations of satellite motion perturbed by extraterrestrial disturbances are solved by means of discretization and appr- imated potential function as well as Gaussian equations. The equations perturbed by geopotential disturbances are solved by symbolic mathematical operations. The traditional problem of singularity in the solutions is solved by so-called singulari- free orbit theory. Simpli?ed disturbed equations of motion are proposed to simplify the solutions. Applications of the theory for analytic orbit determination are also discussed. Indeed, this is the ?rst book since the satellite era, which describes s- tematically the orbit theory with analytical solutions, with respect to all of extrat- restrial and geopotential disturbances of the second order, and the solutions are free of singularity. Based on such a theory, the algorithms of orbit determination can be renewed; deeper insight into the physics of disturbances becomes possible; the way to a variety of new applications and re?nements is opened. My primary knowledge of the orbit theory came from my education of mat- matics while studying physics and theoretical mechanics (1981). My ?rst practical experience with orbit came from the research activity at the Technical University (TU) Berlin on orbit corrections of the satellite altimetry data (1988–1992). The extensive experience on orbit came from the GPS/Galileo software development for orbit determination and geopotential mapping at the GFZ (2001–2004).
