Available in PDF, EPUB and Kindle. Book excerpt: Currently there is considerable interest in flying two or more satellites together because satellite formation flight brings both high reliability and cost reduction for space missions. Satellite formation flight mission takes a long time, so long-term perturbation effects such as Earth oblateness perturbation should be countered to maintain the formation, or the satellite formation would be pulled apart. A satellite with a solar wing receives solar radiation pressure, which can be harnessed in maintaining satellite formation flight. The orbital dynamic characteristics of satellite formation flight using solar wings need to be understood and be exploited in designing the solar wing and controlling formation flight. Our study led to a dynamic model for analyzing out-of-plane relative motion of satellite formation flight, and a formula for sizing the solar wing was derived from the analysis of the dynamic model. Based on a perturbation analysis of the in-plane relative motion, several schemes for maintaining in-plane relative distance were developed to solve the along-track relative motion problem caused by a non-zero wing angle. We also applied feedback control to formation flight, and some effective solar wing steering strategies were developed, starting from a regulator problem. An orbital numerical simulation program was developed based on a formulation of the realistic dynamic models and a special design of the simulation scheme. Our final efforts concentrated on studying some practical issues of interest such as the practical solar radiation pressure model, formation flight of more than two satellites, attitude control considerations.

Book excerpt: Relative motion is a key technology for future missions using formation flying. In my thesis, I have developed three different methods to study it, as function of its representation. Cartesian coordinates have been the main tool to study the relative motions, even if they present some drawbacks in terms of equations linearisation and introduction of perturbations. These limitations can be overcome using differential orbital elements. A third representation of the relative motion is the local orbital elements. They are very interesting to study relative trajectories. The use of differential orbital elements enable the introduction of the main perturbations. For low orbits, the dominant perturbation is the gravity field, and in particular, the oblateness of the Earth. For very high orbits, solar radiation pressure plays a main role when satellites do not have the same ratio surface to mass. The study of relative motion is concluded with the analysis of two missions. First, I have analyzed the interest of formation flying for gravity field determination. In order to do so, I have obtained the sensitivity equations of intersatelllite measurements to geophysical parameters. Second, I have worked on the characteristics of high eccentric orbits (HEO) for formation flying. I have analyzed different aspects of Simbol-X mission.

Available in PDF, EPUB and Kindle. Book excerpt: Space agencies are now realizing that much of what has previously been achieved using hugely complex and costly single platform projects—large unmanned and manned satellites (including the present International Space Station)—can be replaced by a number of smaller satellites networked together. The key challenge of this approach, namely ensuring the proper formation flying of multiple craft, is the topic of this second volume in Elsevier's Astrodynamics Series, Spacecraft Formation Flying: Dynamics, control and navigation. In this unique text, authors Alfriend et al. provide a coherent discussion of spacecraft relative motion, both in the unperturbed and perturbed settings, explain the main control approaches for regulating relative satellite dynamics, using both impulsive and continuous maneuvers, and present the main constituents required for relative navigation. The early chapters provide a foundation upon which later discussions are built, making this a complete, standalone offering. Intended for graduate students, professors and academic researchers in the fields of aerospace and mechanical engineering, mathematics, astronomy and astrophysics, Spacecraft Formation Flying is a technical yet accessible, forward-thinking guide to this critical area of astrodynamics. - The first book dedicated to spacecraft formation flying, written by leading researchers and professors in the field - Develops the theory from an astrodynamical viewpoint, emphasizing modeling, control and navigation of formation flying satellites on Earth orbits - Examples used to illustrate the main developments, with a sample simulation of a formation flying mission included to illustrate high fidelity modeling, control and relative navigation

Available in PDF, EPUB and Kindle. Book excerpt: Small satellite technology is opening up a new era in space exploration offering reduced cost of launch and maintenance, operational flexibility with on-orbit reconfiguration, redundancy etc. The true power of such missions can be harnessed only from close and precise formation flying of satellites. Formation flying missions support diverse application areas such as reconnaissance, remote sensing, solar observatory, deep space observatories, etc. A key component involved in formation flying is the guidance algorithm that should account for system nonlinearities and unknown disturbances. The main focus of this book is to present various nonlinear optimal control and adaptive guidance ideas to ensure precise close formation flying in presence of such difficulties. In addition to in-depth discussion of the relevant topics, MATLAB program files for the results included are also provided for the benefit of the readers. Since this book has concise information about the various guidance techniques, it will be useful reference for researchers and practising engineers in the space field.

Book excerpt: Following on from the hugely successful previous editions, the third edition of Spacecraft Systems Engineering incorporates the most recent technological advances in spacecraft and satellite engineering. With emphasis on recent developments in space activities, this new edition has been completely revised. Every chapter has been updated and rewritten by an expert engineer in the field, with emphasis on the bus rather than the payload. Encompassing the fundamentals of spacecraft engineering, the book begins with front-end system-level issues, such as environment, mission analysis and system engineering, and progresses to a detailed examination of subsystem elements which represent the core of spacecraft design - mechanical, electrical, propulsion, thermal, control etc. This quantitative treatment is supplemented by an appreciation of the interactions between the elements, which deeply influence the process of spacecraft systems design. In particular the revised text includes * A new chapter on small satellites engineering and applications which has been contributed by two internationally-recognised experts, with insights into small satellite systems engineering. * Additions to the mission analysis chapter, treating issues of aero-manouevring, constellation design and small body missions. In summary, this is an outstanding textbook for aerospace engineering and design students, and offers essential reading for spacecraft engineers, designers and research scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Aimed at students, faculty and professionals in the aerospace field, this book provides practical information on the development, analysis, and control of a single and/or multiple spacecraft in space. This book is divided into two major sections: single and multiple satellite motion. The first section analyses the orbital mechanics, orbital perturbations, and attitude dynamics of a single satellite around the Earth. Using the knowledge of a single satellite motion, the translation of a group of satellites called formation flying or constellation is explained. Formation flying has been one of the main research topics over the last few years and this book explains different control approaches to control the satellite attitude motion and/or to maintain the constellation together. The control schemes are explained in the discrete domain such that it can be easily implemented on the computer on board the satellite. The key objective of this book is to show the reader the practical and the implementation process in the discrete domain. - Explains the orbital motion and principal perturbations affecting the satellite - Uses the Ares V rocket as an example to explain the attitude motion of a space vehicle - Presents the practical approach for different control actuators that can be used in a satellite

Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft formation flying (SFF) is of huge importance to the aerospace and space community. Not the stuff of science-fiction, SFF involves flying multiple small satellites together, to deliver benefits which far outweigh a single larger craft or space station. The first autonomous formation flying earth science mission was in 196 and NASA now has 35 SFF mission sets. By networking several smaller and cheaper craft, scientists can make simultaneous measurements that enable higher resolution astronomical imagery, provide robust and fault-tolerant spacecraft system architectures, and enable complex earth science and space science networks dispersed over clusters of satellites in space. This is the first book to introduce and explore SFF. It is a topic of enormous importance to aerospace engineers, astrodynamicists, satellite engineers, astronomers, physicists, and applied mathematicions. This book provides a complete introduction to the subject and is supported by graduate level student exercises plus Matlab and Maple code sets for running SFF simulations. * The first book dedicated to spacecraft formation flying which is the enabling element of distributed spacecraft systems * Written by the leading researchers and teachers in the field; perfect for research and graduate students * Accompanied by Matlab and Maple code sets and exercises for graduate level students of aerospace science, astrodynamics and orbital mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: This volume includes original papers presented at the 4th Symposium on Satellite Dynamics held at the XII Annual Plenary Meeting of COSPAR. At a time where it might be thought that very few problems were left un solved in celestial mechanics, we discover that new and more challenging questions must be answered. The pre cision of observations reaches the centimeter level and physical phenomena which had been disregarded come into play. We need a better treatment of atmospheric drag, radiation forces, and a better knowledge of the earth's gravitational field. Time has to be precisely defined as well as reference systems, including improved values for precision and nutation. The question of resonances introduced by nonzonal harmonics was to be carefully in vestigated. Numerical integration techniques must be optimized and means of controlling their errors improved. Analytical techniques must be made appropriate for com puter processing. Presently existing methods of solu tions of differential equations of interest to celestial mechanics are getting cumbersome as all these new facts come to light. It is clear that entirely new and more effective methods are necessary. These methods must, among other requirements, take into account the essential nonlinear character of the equations. Finally, the mo tion about the center of mass of a satellite is becoming an essential need for the thorough understanding and de scription of the orbital motion.

Available in PDF, EPUB and Kindle. Book excerpt: A study is presented of the interaction with the solar radiation field of a spinning satellite having long flexible rods. The dynamics of thermal bending of the rods is analyzed, including the effect of vehicle rotation, and the shape, amplitude and phase are calculated. The radiation pressure on the periodically bent rods produces a net average despin torque that depends critically on the phase lag of the thermal bending. The theory is compared with flight data from the Alouette I and S48 satellites, and the agreement indicates that the mechanism studied is the primary cause of despin of these vehicles. A means of preventing despin is proposed. It consists of polished plates mounted on the tips of the rods. The torque produced by the solar pressure acting on them is opposite to that on the rods. The plate area required for complete cancellation of the despin torque is of order 1/4 to 1/2 of the projected rod area. (Author).
