At the dawn of the 21st century several Low and Medium Earth Orbit Commercial Satellite constellations will be operational and they will be able to provide high bandwidth Global Communications in voice, data and multimedia services for mobile consumers and also 'users in the move'. This research evolves as a continuation of previous studies (on Iridium, Globalstar, Teledesic and Odyssey), and considers the ICO as well as the Teledesic and GBS systems in an effort to provide a comprehensive model architecture. This model is desired to accommodate the narrow band, wide band and broadcast requirements, respectively, of the U.S. MILSATCOM in addition to the communication needs of a model UN peacekeeping mission. The application of these systems to U.S. MILSATCOM coincides perfectly with the U.S. defense doctrine of a CONUS-based military with the capability of rapid global power projection to respond to crises throughout the global arena. Instead of investing heavily in new satellite systems, the U.S. military services can use the forthcoming commercial LEOs and MEOs systems to meet the information requirements of tactical commanders.

Within the next five years there will be a proliferation of commercial Low Earth Orbit (LEO) satellite systems providing voice/data services to anywhere in the world. Instead of investing heavily in new satellite systems, the military services can use these forthcoming commercial satellite shyster to enhance their existing satellite-based systems. An in-depth study and detailed summary is provided in this thesis for each of the following four commercial LEO satellite systems: Iridium, Teledesic, Odyssey, and Globalstar. Then, a comparison of these systems is performed from the military point of view by using criteria such as antijam protection, security, mobility, flexibility, interoperability, coverage, and capacity. It is shown that an architecture consisting of Globalstar and Odyssey has the potential to provide communications support for DoD's less critical needs which include administration, logistics, and other support functions. Finally , other military applications of these systems are given.

Among the space activities of the last three decades satellite communications (SATCOM) has found the widest application in meeting both civil and military communications requirements. Several international, regional and national SATCOM systems of increasing capacity, capability and complexity have been and are being implemented over the years. The latest versions are utilizing such concepts as spot beams, processing transponders in SS-TDMA and operations in different frequency bands including the EHF band. On the military side, the United States of America, the United Kingdom, France and NATO (the North Atlantic Treaty Organisation) have been the only owners and operators of military SATCOM systems in the West. The systems in being and under development use satellites and ground terminals with characteristics which differ from the civilian ones with respect to frequency bands utilised and survivability and interoperability. The SATCOM has given the military users the potential of having much-needed mobility, flexibility and survivability in strategic and tactical communications for land, sea and air operations. It must, however, be said particularly for the military SATCOM systems that they have been evolved in big jumps, both in time and capability, each jump involving the deployment of two or three often specially designed large satellites, large expenses and rather traumatic transition between jumps. Despite these undesirable features these systems did not have the required degree of suevivability and flexibility.

Extensive revision of the best-selling text on satellite communications — includes new chapters on cubesats, NGSO satellite systems, and Internet access by satellite There have been many changes in the thirty three years since the first edition of Satellite Communications was published. There has been a complete transition from analog to digital communication systems, withanalog techniques replaced by digital modulation and digital signal processing. While distribution of television programming remains the largest sector of commercial satellite communications, low earth orbit constellations of satellites for Internet access are set to challenge that dominance. In the third edition, chapters one through three cover topics that are specific to satellites, including orbits, launchers, and spacecraft. Chapters four through seven cover the principles of digital communication systems, radio frequency communications, digital modulation and multiple access techniques, and propagation in the earth’s atmosphere, topics that are common to all radio communication systems. Chapters eight through twelve cover applications that include non-geostationary satellite systems, low throughput systems, direct broadcast satellite television, Internet access by satellite, and global navigation satellite systems. The chapter on Internet access by satellite is new to the third edition, and each of the chapters has been extensively revised to include the many changes in the field since the publication of the second edition in 2003. Two appendices have been added that cover digital transmission of analog signals, and antennas. An invaluable resource for students and professionals alike, this book: Focuses on the fundamental theory of satellite communications Explains the underlying principles and essential mathematics required to understand the physics and engineering of satellite communications Discusses the expansion of satellite communication systems in areas such as direct-broadcast satellite TV, GPS, and internet access Introduces the rapidly advancing field of small satellites, referred to as SmallSats or CubeSats Provides relevant practice problems based on real-world satellite systems Satellite Communications is required reading for undergraduate and postgraduate students in satellite communications courses and an authoritative reference for engineers working in communications, systems and networks, and satellite operations and management.

Communication Satellite Systems Technology reviews the state of the art in communication satellite systems technology. Topics covered range from commercial point-to-point systems and military satellite communication systems to satellite support subsystems and components, along with high-power systems. Communication satellites are also discussed from a sociological perspective. Comprised of 50 chapters, this book begins with a 1945 article by Arthur C. Clarke in which he proposed the construction of rocket space stations in orbit that would provide complete radio coverage of the globe as well as extraterrestrial relay services. The reader is then introduced to the Early Bird satellite and its hydrogen peroxide orbit control and orientation system. Details of the sequence of maneuvers required after transfer ellipse injection until final placement in a stationary orbit are given. The methods of calculation of maneuver parameters, as well as numerical examples of certain Early Bird orbit changes and maneuver parameters, are described. The effects of the principal long-term disturbing forces on the satellite are also considered. Subsequent chapters focus on military satellite communication systems; satellite support subsystems and components; high-power systems; and systems concepts. The organization and program of Intelsat are also evaluated. This monograph will be of value to practitioners in the fields of aeronautics, astronautics, and satellite communications.

Near-earth space, which extends to geosynchronous orbits where satellites remain faithfully over a fixed spot on the ground, does not lend itself to romantic fantasies of science fiction. It is a working place from which services can be delivered with ease and efficiency. Meteorology, seismic and crop-yield predictions, environmental monitoring, communications of all sorts, guidance and navigation, medical and educational services, treaty verification and photographic reconnaissance, news-gathering, scientific observation across the entire electromagnetic spectrum, prospecting, remote sensing, and monitoring of human activities are all in a day's work for near-earth space. Global cellular telephony, only a few years ago the exclusive privilege of comic-book heroes, is becoming a space-based commonplace. Planes that land in fog and cars that find their way in the labyrinthine streets of Tokyo guided from space are beyond a near horizon. Space is delivering its promise. This volume describes many of these activities and their prospects for changing the way we live, communicate, and travel on this Earth.
