Book excerpt: This paper presents a numerical method to rapidly determine the rise- set times of satellite-satellite and satellite ground station visibility periods, with the line-of-sight corrected for an oblate Earth. The algorithm uses space curve modeling technique known as parabolic blending to construct the waveform of the visibility function, psi (t), versus time. The waveform is produced from either uniform or arbitrarily spaced abscissa points, from which rise-set times are obtained by extracting the real roots of a localized cubic polynomial. This algorithm works for all orbital eccentricities and perturbed satellite motion, provided the visibility function, psi(t), does not become discontinuous as it could from thrusting or deploying a tether. For this study, the rise-set truth table is constructed using a standard five second step-by- step integration with a linear interpolator to locate the exact crossing times. ne simulation results from this algorithm are almost identical to those obtained by modeling satellites subject to first order secular perturbations caused by mass anomalies, but generated in considerably less time. Advantages of this numerical method include compact storage and ease of calculation, making it attractive for supporting ground-based and autonomous onboard satellite operations ...

Book Synopsis Fundamentals of Astrodynamics and Applications by : D.A. Vallado
Download or read book Fundamentals of Astrodynamics and Applications written by D.A. Vallado and published by Springer Science & Business Media. This book was released on 2001-06-30 with total page 1002 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Astrodynamics and Applications is rapidly becoming the standard astrodynamics reference for those involved in the business of spaceflight. What sets this book apart is that nearly all of the theoretical mathematics is followed by discussions of practical applications implemented in tested software routines. For example, the book includes a compendium of algorithms that allow students and professionals to determine orbits with high precision using a PC. Without a doubt, when an astrodynamics problem arises in the future, it will become standard practice for engineers to keep this volume close at hand and `look it up in Vallado'. While the first edition was an exceptionally useful and popular book throughout the community, there are a number of reasons why the second edition will be even more so. There are many reworked examples and derivations. Newly introduced topics include ground illumination calculations, Moon rise and set, and a listing of relevant Internet sites. There is an improved and expanded discussion of coordinate systems, orbit determination, and differential correction. Perhaps most important is that all of the software routines described in the book are now available for free in FORTRAN, PASCAL, and C. This makes the second edition an even more valuable text and superb reference.

Book Synopsis Rapid Determination of Satellite Orbits from Doppler Data by : Robert R. Newton
Download or read book Rapid Determination of Satellite Orbits from Doppler Data written by Robert R. Newton and published by . This book was released on 1963 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the orbit determination procedure described in this paper, the set of physical quantities fitted in the computations is not the set of basic measurements made by the ground stations. Rather, it uses the basic measurements on a pass-by-pass basis, together with a preliminary estimate of the orbit, to determine a fictitious position of the tracking station for each pass. It can be shown that the error in station position is also a representation of the error in satellite position at the center time of the pass. Thus, for each pass, a new estimate of satellite position is formed, and a new orbit is chosen to fit these positions. It should be possible to apply this method to any type of tracking data. With Doppler data, the convergence of the orbit determination position is much faster than that of the conventional method. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of a symposium on Dynamics of satellites which took place in Prague in May 1969 during the twelfth COSPAR meeting. This symposium was sponsored by the International Astronomical Union, the International Association of Geodesy, the International Union of Theoretical and Applied Mechanics and COSPAR (Committee on Space Research). The organizing committee was composed of Dr. KOVALEVSKY chair man, Dr. Yu. V. BATRAKOV representing IAU, Dr. A. H. COOK for lAG, Dr. D. KING-HELE for COSPAR, Prof. M. Roy for IUTAM and Dr. ROSENBERG. I wish to take advantage of the opportunity to thank, on behalf of all the participants, the organizing committee members, Prof. BUCHAR, Dr. RAJSK:I and Dr. SEHNAL, for the kindness and efficiency of their welcome. The interpreters who translated with virtuosity during the whole symposium also deserve our gratitude. I am grateful also for the care and skill with which Springer-Verlag has printed this volume.
