  • Spacecraft Trajectories in a Sun, Earth, and Moon Ephemeris Model
    SPACECRAFT TRAJECTORIES IN A SUN, EARTH, AND MOON EPHEMERIS MODEL A Project Presented to The Faculty of the Department of Aerospace Engineering San José State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Aerospace Engineering by Romalyn Mirador i ABSTRACT SPACECRAFT TRAJECTORIES IN A SUN, EARTH, AND MOON EPHEMERIS MODEL by Romalyn Mirador This project details the process of building, testing, and comparing a tool to simulate spacecraft trajectories using an ephemeris N-Body model. Different trajectory models and methods of solving are reviewed. Using the Ephemeris positions of the Earth, Moon and Sun, a code for higher-fidelity numerical modeling is built and tested using MATLAB. Resulting trajectories are compared to NASA’s GMAT for accuracy. Results reveal that the N-Body model can be used to find complex trajectories but would need to include other perturbations like gravity harmonics to model more accurate trajectories. i ACKNOWLEDGEMENTS I would like to thank my family and friends for their continuous encouragement and support throughout all these years. A special thank you to my advisor, Dr. Capdevila, and my friend, Dhathri, for mentoring me as I work on this project. The knowledge and guidance from the both of you has helped me tremendously and I appreciate everything you both have done to help me get here. ii Table of Contents List of Symbols ............................................................................................................................... v 1.0 INTRODUCTION

As originally intended, this handbook is designed to serve as a reference manual for policy makers, program managers, educators, engineers, and scientists alike. It contains information for the uninitiated, providing insight into the fundamental behavior of tethers in space. For those familiar with space tethers, it summarizes past and ongoing studies and programs, a complete bibliography of tether publications, and names, addresses, and phone numbers of workers in the field. Perhaps its most valuable asset is the brief description of nearly 50 tether applications which have been proposed and analyzed over the past 10 years.

  • Uncertainties and Instabilities in Celestial Mechanics
    Particle Accelerators, 1986, Vol. 19, pp. 43-47 0031-2460/86/1904-0043/$10.00/0 © 1986 Gordon and Breach, Science Publishers, S.A. Printed in the United States of America UNCERTAINTIES AND INSTABILITIES IN CELESTIAL MECHANICS VICTOR SZEBEHELY University of Texas, Austin, TX 78712 (Received March 7, 1985) Uncertainty and instability are closely associated properties of the dynamical systems of celestial mechanics. The short time predictions of celestial mechanics concerning· the stellar universe when compared to the long-lived atomic universe seem to be simple problems according to our old-fashioned ideas. In fact, modern celestial mechanics is known to be nondeterministic due to uncertainties in modeling, due to unsatisfactory information concerning initial conditions, and because of the global nonintegrable nature of the equations. Instabilities, inherently embedded even in our simplest systems, make determinsitic predictions into unrealistic expectations. I. INTRODUCTION Computations in celestial mechanics may be compared to those in accelerators when the pertinent numbers of revolutions are evaluated. The earth makes one revolution around the sun in one year. Our predictions concerning the orbits of the planets are considered at present reliable for 106 years, and the age of the system is estimated to be approximately 109 years. In other words, our computational competence in celestial mechanics is limited by 106 revolutions. At the other extreme are the hydrogen atoms in the ground state with 3 x 1023 revolutions per year and the particles in accelerators with 6 x 1010 revolutions per year. Comparing the motion in accelerators with the solar system where 106 seems to be the computational limit, one arrives at a corresponding limit of approximately 8 minutes.

Victor was admired and respected throughout the celestial mechanics and aerospace community. His contributions were both fundamental and extensive. His unassuming manner, which concealed a giant intellect, endeared him to all his colleagues and students. Victor was born in Budapest, Hungary, in 1921. He managed to survive the Nazi occupation as a student and professor at the Technical University of Budapest. He received his M.S. degree in mechanical engineering in 1943 and his doctor of science degree in 1945 with a dissertation on the “three-body problem.” (It would be almost twenty years before he would return to this most favored topic.) He was an assistant professor during the last years of the war, teaching mathematics and writing five books. between 1944 and 1947: Calculus for Engineers (two volumes with two editions), Exercise in Analysis (two volumes), and GraphicalMethods in Applied Mathematics. Then he immigrated to Canada— one of a generation of scientists who emigrated from Europe after World War II. (I don’t remember Victor ever talking about life in Hungary in the war years, but he did keep in touch with many colleagues there throughout his life.) Copyright National Academy of Sciences.

    On the Stability of Quasi-Satellite Orbits in the Elliptic Restricted Three-Body Problem Application to the Mars-Phobos System Francisco da Silva Pais Cabral Dissertação para a obtenção de Grau de Mestre em Engenharia Aeroespacial Júri Presidente: Prof. Doutor Fernando José Parracho Lau Orientador: Prof. Doutor Paulo Jorge Soares Gil Vogal: Prof. Doutor João Manuel Gonçalves de Sousa Oliveira Dezembro de 2011 Acknowledgments The author wishes to acknowledge His thesis coordinator, Prof. Paulo Gil, for, one, presenting this thesis opportunity in the author’s field of interest and, second, for the essential orientation provided to the author that made this very same thesis possible, His professors, both in IST and TU Delft, for the acquired knowledge and transmitted passion in the most diverse fields, His university, IST, for providing the means to pursue the author’s academic and professional goals, His colleagues for their support and availability to discuss each others’ works, His friends for keeping the author sane. iii Abstract In this thesis, the design of quasi-satellites orbits in the elliptic restricted three-body problem is ad- dressed from a preliminary space mission design perspective. The stability of these orbits is studied by an analytical and a numerical approach and findings are applied in the study of the Mars-Phobos system. In the analytical approach, perturbation theories are applied to the solution of the unperturbed Hill’s equations, obtaining the first-order approximate averaged differential equations on the osculating elements. The stability of quasi-satellite orbits is analyzed from these equations and withdrawn conclu- sions are confirmed numerically.
