Creation of a fundamentally new technical capability ideally begins with the recognition of some future need, a careful description of requirements, development, testing, and operational implementation. In contrast to this ideal situation, the launch of the Sputnik 1 satellite on 4 October 1957 created an immediate need within the United States to track and maintain a catalog of orbital elements for artificial Earth satellites. This required inventing a solution to a problem that did not even exist prior to 1957. Thus, the initial effort was driven both by external circumstances and by highly constrained solution options such as computing and data communications capacities. This external event-driven paradigm has continued to be the case to this day. Describing the system evolution based on a small mix of planning and far larger mix of reaction to external circumstance, in fact, makes a very interesting story.This book begins with an introduction that provides a snapshot collection of episodes from the first half century of space surveillance that illustrates how events drove invention. The narrative describes how external problems arose, demanding near real-time adaptation and invention to maintain the satellite catalog and provide timely space situational awareness.The main elements of space surveillance are then discussed separately, such as key people and organizations, orbit models, computing systems, observing sites, networks, and international relationships. The book concludes with an Epilogue briefly discussing the prospects and problems facing the future space surveillance mission. Aimed at engineers and specialists in space surveillance as well as general readers, this systematic historical account broadens and clarifies understanding of this fascinating, vitally important, and often underappreciated field.

This textbook provides details of the derivation of Lagrange's planetary equations and of the closely related Gauss's variational equations, thereby covering a sorely needed topic in existing literature. Analytical solutions can help verify the results of numerical work, giving one confidence that his or her analysis is correct. The authors—all experienced experts in astrodynamics and space missions—take on the massive derivation problem step by step in order to help readers identify and understand possible analytical solutions in their own endeavors. The stages are elementary yet rigorous; suggested student research project topics are provided.After deriving the variational equations, the authors apply them to many interesting problems, including the Earth-Moon system, the effect of an oblate planet, the perturbation of Mercury's orbit due to General Relativity, and the perturbation due to atmospheric drag. Along the way, they introduce several useful techniques such as averaging, Poincaré's method of small parameters, and variation of parameters. In the end, this textbook will help students, practicing engineers, and professionals across the fields of astrodynamics, astronomy, dynamics, physics, planetary science, spacecraft missions, and others.“An extensive, detailed, yet still easy-to-follow presentation of the field of orbital perturbations.”- Prof. Hanspeter Schaub, Smead Aerospace Engineering Sciences Department, University of Colorado, Boulder“This book, based on decades of teaching experience, is an invaluable resource for aerospace engineering students and practitioners alike who need an in-depth understanding of the equations they use.”- Dr. Jean Albert Kéchichian, The Aerospace Corporation, Retired“Today we look at perturbations through the lens of the modern computer. But knowing the why and the how is equally important. In this well organized and thorough compendium of equations and derivations, the authors bring some of the relevant gems from the past back into the contemporary literature.”- Dr. David A Vallado, Senior Research Astrodynamicist, COMSPOC“The book presentation is with the thoroughness that one always sees with these authors. Their theoretical development is followed with a set of Earth orbiting and Solar System examples demonstrating the application of Lagrange’s planetary equations for systems with both conservative and nonconservative forces, some of which are not seen in orbital mechanics books.”- Prof. Kyle T. Alfriend, University Distinguished Professor, Texas A&M University
