This book was released on 2013-12-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Czech edition was published four years ago, the authors have revised the original text tobring it up to date. During these four years, thanks to satellite altimetry the accuracy of the global descrip tion of the gravity field (model GEM-T2), of the fundamental astro geodetic constants, of the principal moments of inertia of the Earth and, in particular, of their differences, of the precession constant, and of a number of other dynamical parameters of the Earth have been improved. The authors have included most of these improvements in the revised English edition. They have, of course, also made factual, formal and other corrections and have modified some of the figures. Additions to the index and references have also been made. Praha, Czech Republic M. BuRSA and K.

This book was released on 1970 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lindstedt perturbation method is applied to the motion of an artificial Earth satellite that moves along a geodesic of the Schwarzschild metric of general relativity. The purpose of this analysis is to determine the extent to which general-relativistic effects are detectable in range measurements of Earth-orbiting spacecraft.

Download or read book Theory of Geostationary Satellites written by Chong-Hung Zee and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geostationary or equatorial synchronous satellites are a daily reminder of our space efforts during the past two decades. The nightly television satellite weather picture, the intercontinental telecommunications of television transmissions and telephone conversations, and the establishrnent of educational programs in remote regions on Earth are constant reminders of the presence of these satellites. As used here, the term 'geo stationary' must be taken loosely because, in the long run, the satellites will not remain 'stationary' with respect to an Earth-fixed reference frame. This results from the fact that these satellites, as is true for all satellites, are incessantly subject to perturbations other than the central-body attraction of the Earth. Among the more predominant pertur bations are: the ellipticity of the Earth's equator, the Sun and Moon, and solar radiation pressure. Higher harmonics of the Earth's potential and tidal effects also influence satellite motion, but they are of second order when compared to the predominant perturbations. This volume deals with the theory of geostationary satellites. It consists of seven chapters. Chapter 1 provides a general discussion including a brief history of geostationary satellites and their practical applications. Chapter 2 describes the Earth's gravitational potential field and the methodology of solving the geostationary satellite problem. Chapter 3 treats the effect of Earth's equatorial ellipticity (triaxiality) on a geostationary satellite. Chapter 4 deals with the effects of the Sun and Moon on the satellite's motion while Chapter 5 presents the combined influences of the Sun, Moon and solar radiation pressure. Chapter 6 describes various station-keeping techniques which may be used to make geostationary satellites practically stationary. Finally, Chapter 7 describes the verification of the theory developed in Chapters 3, 4 and 5 by utilizing the Early Bird synchronous satellite observed data as well as its numerically integrated results.

Download or read book Theory Of Orbital Motion written by Tan Arjun and published by World Scientific Publishing Company. This book was released on 2008-01-04 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orbital motion is a vital subject which has engaged the greatest minds in mathematics and physics from Kepler to Einstein. It has gained in importance in the space age and touches every scientist in any field of space science. Still, there is almost a total dearth of books in this important field at the elementary and intermediate levels — at best a chapter in an undergraduate or graduate mechanics course.This book addresses that need, beginning with Kepler's laws of planetary motion followed by Newton's law of gravitation. Average and extremum values of dynamical variables are treated and the central force problem is formally discussed. The planetary problem in Cartesian and complex coordinates is tackled and examples of Keplerian motion in the solar system are also considered. The final part of the book is devoted to the motion of artificial Earth satellites and the modifications of their orbits by perturbing forces of various kinds.

Available in PDF, EPUB and Kindle. Book excerpt: International Geophysics Series, Volume 10: The Gravity Field of the Earth: From Classical and Modern Methods explores the theory of the gravity field of the earth based on both classical and modern methods. Classical method involves observations of gravity taken over the earth's surface, while the modern method uses observations of variation of orbital elements of artificial satellites caused by the gravity field of the earth. This book is organized into two parts encompassing 12 chapters. Part I describes the solution of physical problems that are treated as Dirichlet problems or solved by means of integral equations. This part also deals with the determination of the geoid form from ground gravity measurements using the Stokes formula. The method of obtaining the Stokes formula by means of an integral equation is also outlined. Part II contains modern mathematical techniques developed to utilize the observations of artificial satellites for geodetic purposes. This book could be used as a textbook for students in the fields of geodesy, geophysics, or astronomy.

Download or read book Torques and Attitude Sensing in Earth Satellites written by S. Fred Singer and published by Elsevier. This book was released on 2012-12-02 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applied Mathematics and Mechanics, Volume 7: Torques and Attitude Sensing in Earth Satellites focuses on the possible torques that can affect the angular momentum of an Earth satellite. This book provides an understanding of the environment in which a satellite operates. Organized into 16 chapters, this volume starts with an overview of the application of force-free motion to space programs. This text then discusses the torque effects of a gravitational field, particularly with its gradient. Other chapters consider a particular method of gravity-gradient stabilization that utilizes a passive device to damp librations and thereby attain a vertical orientation. This book discusses as well the effects of the geomagnetic field on the angular motion of a satellite. The reader is also introduced to the method of magnetic attitude control employed in the Tiros satellite. The final chapter deals with the problem of horizon sensing, which is important for satellites requiring Earth stabilization. Astrophysicists will find this book useful.
