Presents the theories and applications of determining theposition of an object in space through the use ofsatellites As the importance of space reconnaissance technologyintensifies, more and more countries are investing money inbuilding their own space reconnaissance satellites. Due to thesecrecy and sensitivity of the operations, it is hard to findpublished papers and journals on the topic outside of military andgovernmental agencies. This book aims to fill the gap bypresenting the various applications and basic principles of a verymodern technology. The space electronic reconnaissance system inmono/multi-satellite platforms is a critical feature which can beused for detection, localization, tracking or identification of thevarious kinds of signal sources from radar, communication ornavigation systems. Localization technology in space electronic reconnaissance usessingle or multiple satellite receivers which receive signals fromradar, communication and navigation emitters in the ground, oceanand space to specify the location of emitter. Themethods, principles and technologies of different space electronicreconnaissance localization systems are introduced in this book, asare their performances, and the various methods are explained andanalysed. Digital simulations illustrate the results. Presents the theories and applications of determining theposition of an object in space through the use of satellites Introduces methods, principles and technologies of localizationand tracking in the space electronic reconnaissance system, thelocalization algorithm and error in satellite system and near spaceplatform system, and the tracking algorithm and error in singlesatellite-to-satellite tracking system Provides the fundamentals, the mathematics, the limitations,the measurements, and systems, of localization with emphasis ondefence industry applications Highly relevant for Engineers working in avionics, radar,communication, navigation and electronic warfare. Chapters include:- the introduction of space electronicreconnaissance localization technology, knowledge about thesatellite orbit and basic terminology of passive localization,single satellite geolocation technology based on direction finding,three-satellite geolocation technology based on time difference ofarrival (TDOA), two-satellite geolocation technology based on TDOAand frequency difference of arrival (FDOA), the single satellitelocalization technology based on kinematics theory, localizationprinciples of near-space platform electronic reconnaissancesystems, the orbit determination of single satellite-to-satellitetracking using bearings only(BO) information, the orbitdetermination of single satellite-to-satellite tracking usingbearings and frequency information, the orbit determination ofsingle satellite-to-satellite tracking using frequency only(FO)information. Each chapter ends with a problem and solution section,some using Matlab code.
The authors, leading representatives of Russian space research and industry, show the results and future prospects of astronautics at the start of the third millennium. The focus is on the development of astronautics in Russia in the new historical and economic conditions. The text spotlights the basic trends in space related issues before moving on to describe the possibilities of the wide use of space technologies and its numerous applications such as navigation and communication, space manufacturing, and space biotechnology. The book contains a large amount of facts described in a way understandable without specialist knowledge. The text is accompanied by many photographs, charts and diagrams, mostly in color.
This book, first published in 1978, examines the military use of space – around 60 per cent of US and Soviet satellites were military ones. The satellites were for military communications, weather prediction, navigation, photographic and electronic reconnaissance, targeting, early warning, and satellites capable of destroying enemy satellites. This book analyses the capabilities of military satellites as part of the debate around the encroachment of military technology and purposes into space.
Space has become increasingly crowded since the end of the Cold War, with new countries, companies, and even private citizens operating satellites and becoming spacefarers. This book offers general readers a valuable primer on space policy from an international perspective. It examines the competing themes of space competition and cooperation while providing readers with an understanding of the basics of space technology, diplomacy, commerce, science, and military applications. The recent expansion of human space activity poses new challenges to existing treaties and other governance tools for space, increasing the likelihood of conflict over a diminishing pool of beneficial locations and resources close to Earth. Drawing on more than twenty years of experience in international space policy debates, James Clay Moltz examines possible avenues for cooperation among the growing pool of space actors, considering their shared interests in space traffic management, orbital debris control, division of the radio frequency spectrum, and the prevention of military conflict. Moltz concludes with policy recommendations for enhanced international collaboration in space situational awareness, scientific exploration, and restraining harmful military activities.
Distilling complex theoretical physical concepts into an understandable technical framework, Next-Generation Batteries and Fuel Cells for Commercial, Military, and Space Applications describes primary and secondary (rechargeable) batteries for various commercial, military, spacecraft, and satellite applications for covert communications, surveillan
Forfatterne hævder, at den hurtige udvikling af rumbaserede våben, bl.a. til forsvar mod atommissiler, på den ene side kan gøre atomvåben overflødige, på den anden side kan øge risikoen for en atomkrig.
The year 2007 saw the fiftieth anniversary of the Space Age, which began with the launching of Sputnik by the Soviet Union in October 1957. Space is crucial to the politics of the postmodern world. It has seen competition and cooperation in the past fifty years, and is in danger of becoming a battlefield in the next fifty. The International Politics of Space is the first book to bring these crucial themes together and provide a clear and vital picture of how politically important space has become, and what its exploitation might mean for all our futures. Michael Sheehan analyzes the space programmes of the United States, Russia, China, India and the European Space Agency, and explains how central space has become to issues of war and peace, international law, justice and international development, and cooperation between the worlds leading states. It highlights the significance of China and India’s commitment to space, and explains how the theories and concepts we use to describe and explain space are fundamental to the possibility of avoiding conflict in space in the future.
From the front jacket flap: Contrary to widespread expectations in the wake of Sputnik, outer space did not immediately become a new arena for a superpower arms competition. Although the United States and the Soviet Union began to use space extensively for military purposes, both exhibited relatively little interest in the development of space weaponry. By the beginning of the 1980s, however, an arms race in space seemed inevitable. Now both the United States and the Soviet Union have developed the means to disable satellites and are now also considering the deployment of ballistic missile defenses in space. Why were these weapons never extensively developed earlier? What changed in the late 1970s to reverse the predominant trend in the militarization of space? What are the lessons for arms control and for Soviet-American relations in general? Paul Stares addresses these fundamental questions by examining the factors that have shaped United States policy towards the military use of space and in particular the development of antisatellite weapons. States relies heavily on declassified documents found in Presidential libraries and made available under the Freedom of Information Act, and he obtained additional information from a comprehensive series of interview with former members of the U.S. government and armed services. By judicious use of this material, he provides the first detailed account of United States space weapons policy and programs. An invaluable source of information for defense analysts and scholars of international relations, The Militarization of Space is essential reading for anyone wishing to understand present United States military space policy and its implications for the future.
