Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to a congressional request, GAO reviewed the Department of Defense's (DOD) plans for military communications satellites, focusing on: (1) alternatives contained in its 1991 military satellite communications architecture study; (2) development of low-cost technologies for future satellite systems; and (3) plans to implement follow-on satellite acquisitions. GAO found that: (1) the DOD study identified 12 alternatives for its communications satellite needs; (2) DOD chose the second-highest-cost alternative because of high mission supportability and the low to moderate program and system transition risk; (3) other alternatives, specifically the common bus designs, could satisfy DOD communications requirements at a significantly lower cost; (4) DOD lacks a coordinated process to implement modern satellite technology; (5) DOD development of the dual common bus technology is at a more advanced stage than single common bus technology development; (6) DOD could introduce modern technology into its defense satellite communications system plans by including a dual common bus capability and revising launch schedules to avoid an excessive number of satellites in orbit at any one time; and (7) DOD could replace its Milstar satellites with the dual common bus design and reduce the costs of the other satellite systems by inserting modern technology into its existing communications systems.

Download or read book Employing Commercial Satellite Communications: Wideband Investment Options for the Department of Defense written by and published by . This book was released on 2000 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Defense (DoD) is considering major investments in systems that exploit information to support warfighting, and communications between users around the globe will be key to transmitting and using this information. In the near term, there are not enough military systems to satisfy projected communications demand and commercial systems will have to be used. In the future, budgetary pressures will make it difficult for the services to satisfy the projected communications demand with dedicated military assets. This report seeks to answer several questions: 1) How much of the projected demand can be met with programmed and planned military assets?; 2) Can commercial technologies, systems, or services meet the remaining needs? How do commercial communication assets compare with military assets in their ability to meet criteria important to DoD? What steps might be taken to mitigate shortfalls?; 3) What is the expected cost of providing the projected communications demand?; and, 4) What investment strategies should DoD employ to minimize the expected cost? The many categories of military communications include everything from battlefield communications between mobile users to communications between fixed sites in rear areas. Some of these communications must be survivable in a nuclear war, and others need high levels of protection from detection, interception, or jamming. Some require verv high data rates, whereas others need only low data rates. Some communications can be by wire or fiber optic cable, whereas others must use wireless means. We have examined a specific category of communications-high bandwidth, minimally protected satellite communications. This category of military demand represents roughly half of the projected military satellite capacity needs. To the extent that use of commercial systems can satisfy this need, military systems can be used for more specialized communications needing a greater level of control over their operation.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005-07-18 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States must operate successfully in space to help assure its security and economic well being. The Department of the Navy is a major user of space capabilities, although those capabilities are now primarily provided by DOD, the Air Force, and NOAA. Following a DOD assessment of national space security management in 2001, the Navy commissioned a Panel to Review Space to assess Navy space policy and strategy. As an extension of that review, the NRC was requested by the Navy to examine its needs in space for providing future operational and technical capabilities. This report presents a discussion of the strategic framework of future space needs, the roles and responsibilities for meeting those needs, an assessment of Navy support to space mission areas, and a proposed vision for fulfilling Naval forces space needs.
