Book Synopsis Attitude Determination of Triad and TIP-II and -III Gravity-Gradient-Stabilized Satellites by : C. E. Williams
Download or read book Attitude Determination of Triad and TIP-II and -III Gravity-Gradient-Stabilized Satellites written by C. E. Williams and published by . This book was released on 1977 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The attitude of a satellite refers to the rotational orientation of the spacecraft relative to some reference triad of Cartesian axes (these being, for the type of spacecraft treated here, the orbit radius vector, the normal-to-the-orbit plane, and the vector cross product of the two). Mathematically, the attitude is usually represented by nine direction cosines and/or three Euler angles. The numerical determination of these parameters is the objective of attitude estimation. Various schemes have been developed and used by the Applied Physical Laboratory to determine the attitude performance of its satellites. In recent years, a least-squares technique that involves eigenvalue and eigenvector computation has been added. This report presents the formulation of the technique and discusses its successful application. Attitude estimation results from three orbiting spacecraft are included. (Author).
Book Synopsis A System for Passive Gravity-gradient Stabiliza Tion of Earth Satellites by : Robert E. Fischell
Download or read book A System for Passive Gravity-gradient Stabiliza Tion of Earth Satellites written by Robert E. Fischell and published by . This book was released on 1963 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The satellite 1963 22A was successfully captured into a condition of passive, gravity-gradient stabilization. All elements of the stabilization system, including magnetic dispin, magnetic orientation devices, the extendible boom, the damping spring, and the attitude detection system performed satisfactorily. An unexpected high frequency oscillation of the boom and satellite system was observed which was most probably a dynamic effect resulting from thermal bending. This has caused the satellite to stabilize with a maximum deviation off the vertical of approximately 10 degrees. The objective of the gravity-gradient stabilization for the 22A satellite was to have the antennas directed downward within 20 degrees of the local vertical at all times. This objective has been successfully accomplished by the satellite's passive gravity-gradient attitude stabilization system. (Author).
Book Synopsis Attitude Stabilization for CubeSat by : Mohammed Chessab Mahdi
Download or read book Attitude Stabilization for CubeSat written by Mohammed Chessab Mahdi and published by Cambridge Scholars Publishing. This book was released on 2018-11-14 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores CubeSat technology, and develops a nonlinear mathematical model of a spacecraft with the assumption that the satellite is a rigid body. It places emphasis on the CubeSat subsystem, orbit dynamics and perturbations, the satellite attitude dynamic and modeling, and components of attitude determination and the control subsystem. The book focuses on the attitude stabilization methods of spacecraft, and presents gravity gradient stabilization, aerodynamic stabilization, and permanent magnets stabilization as passive stabilization methods, and spin stabilization and three axis stabilization as active stabilization methods. It also discusses the need to develop a control system design, and describes the design of three controller configurations, namely the Proportional–Integral–Derivative Controller (PID), the Linear Quadratic Regulator (LQR), and the Fuzzy Logic Controller (FLC) and how they can be used to design the attitude control of CubeSat three-axis stabilization. Furthermore, it presents the design of a suitable attitude stabilization system by combining gravity gradient stabilization with magnetic torquing, and the design of magnetic coils which can be added in order to improve the accuracy of attitude stabilization. The book then investigates, simulates, and compares possible controller configurations that can be used to control the currents of magnetic coils when magnetic coils behave as the actuator of the system.

Book Synopsis Spacecraft Attitude Determination and Control by : J.R. Wertz

This book was released on 2012-12-06 with total page 877 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roger D. Werking Head, Attitude Determination and Control Section National Aeronautics and Space Administration/ Goddard Space Flight Center Extensiye work has been done for many years in the areas of attitude determination, attitude prediction, and attitude control. During this time, it has been difficult to obtain reference material that provided a comprehensive overview of attitude support activities. This lack of reference material has made it difficult for those not intimately involved in attitude functions to become acquainted with the ideas and activities which are essential to understanding the various aspects of spacecraft attitude support. As a result, I felt the need for a document which could be used by a variety of persons to obtain an understanding of the work which has been done in support of spacecraft attitude objectives. It is believed that this book, prepared by the Computer Sciences Corporation under the able direction of Dr. James Wertz, provides this type of reference. This book can serve as a reference for individuals involved in mission planning, attitude determination, and attitude dynamics; an introductory textbook for stu dents and professionals starting in this field; an information source for experimen ters or others involved in spacecraft-related work who need information on spacecraft orientation and how it is determined, but who have neither the time nor the resources to pursue the varied literature on this subject; and a tool for encouraging those who could expand this discipline to do so, because much remains to be done to satisfy future needs.

Book Synopsis Gravity-gradient Attitude Stabilization for Communication Satellites by : Frederick F. Mobley
Download or read book Gravity-gradient Attitude Stabilization for Communication Satellites written by Frederick F. Mobley and published by . This book was released on 1964 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gravity-gradient attitude stabilization has been used successfully in a number of near-earth satellites in recent months. After the pioneering effort of the Applied Physics Laboratory in the first successful demonstration of gravity stabilization in June 1963, this technique has become one of the basic elements of satellite technology. By January of 1964 three APL satellites had been vertically stabilized by the passive gravity-gradient technique, and are expected to continue in this state indefinitely. A satellite of the Naval Research Laboratory was also stabilized successfully in January 1964. These developments are reviewed herein, and the problems of extending these techniques to higher altitude for use as communication satellites are discussed. (Author).
