This book was released on 1998-09-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Success in modem military operations now depends upon the connectivity provided by communication systems. Space-based communication assets, due to their accessibility, coverage, flexibility, and global reach, are in many cases the only practical means to support transportable and mobile warfighter requirements. Joint Vision 2010's view of future warfighting and its higher, complex operational tempos will demand unprecedented distribution of information, for rapid warfighter interaction, battlefield coordination and joint interoperability. The increasing lethality, mobility and range of weapons, coupled with a smaller and more dispersed force structure, result in significantly increased amounts of three-dimensional battlespace over which an individual force element must maintain awareness and control. The end result is a lethal, deployable military, which is dependent on high-volume information transfers, most of which are graphical, pictorial, or data-intensive in nature. Information, and speed of delivery, are driving the warfighter's demand for higher capacity, wideband satellite communications systems. It is the focus of this research to assist DoD in ascertaining the correct, affordable mix of DoD owned SATCOM and commercial SATCOM that can best meet the warfighter's growing information requirements. The Teledesic Wideband Satellite Communication System is examined for future integration into the DoD MILSATCOM architecture and its military applications. Failure to provide the requisite amounts of communications to the right users when and where required will prevent a full return on the investment in advanced weapons, sensor platforms and combat support systems. Recognizing this, DOD needs to make an investment in Teledesic and other information age throughput technologies.

This book was released on 2016-09-30 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not yet 60 years since the first artificial satellite was placed into Earth orbit. In just over a half century, mankind has gone from no presence in outer space to a condition of high dependence on orbiting satellites. These sensors, receivers, transmitters, and other such devices, as well as the satellites that carry them, are components of complex space systems that include terrestrial elements, electronic links between and among components, organizations to provide the management, care and feeding, and launch systems that put satellites into orbit. In many instances, these space systems connect with and otherwise interact with terrestrial systems; for example, a very long list of Earth-based systems cannot function properly without information from the Global Positioning System (GPS). Space systems are fundamental to the information business, and the modern world is an information-driven one. In addition to navigation (and associated timing), space systems provide communications and imagery and other Earth-sensing functions. Among these systems are many that support military, intelligence, and other national security functions of the United States and many other nations. Some of these are unique government, national security systems; however, functions to support national security are also provided by commercial and civil-government space systems. 
The importance of space systems to the United States and its allies and potential adversaries raises major policy issues. National Security Space Defense and Protection reviews the range of options available to address threats to space systems, in terms of deterring hostile actions, defeating hostile actions, and surviving hostile actions, and assesses potential strategies and plans to counter such threats. This report recommends architectures, capabilities, and courses of action to address such threats and actions to address affordability, technology risk, and other potential barriers or limiting factors in implementing such courses of action.

Download or read book United States Military Space Into the Twenty First Century written by and published by DIANE Publishing. This book was released on 2002 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the 42nd volume in the Occasional Paper series of the U.S. Air Force Institute for National Security Studies (INSS). This volume presents two important papers on United States military space. The first paper, "What is Spacepower and Does It Constitute a Revolution in Military Affairs?", examines the concept of "spacepower" as it is emerging within the U.S. military and business sectors to establish the basis for military space roles and implications. It also posits military-commercial sector linkages as the best near-term road map for future development. As commercial activities expand the importance of United States space, and as technological advances enable military missions, Hays sees expanded military roles, including space weaponization, on the horizon. He concludes that military space has already had a significant impact on the American way of war. That trend will only continue as the promise of a true space-led revolution in military affairs awaits eventual space weaponization. Given an increasingly important U.S. commercial and military presence in space, the second paper, "Space-Related Arms Control and Regulation to 2015: Precedents and Prospects," presents a detailed analysis of existing regulations and controls that constrain and shape military space use and development. It also presents a comprehensive examination of current and future issues that will define likely arenas of international efforts to further control military space. The United States must be very aware of the possible consequences for its overall commercial and military space efforts in addressing these issues. Finally, the paper suggests areas where some current regulatory emphasis could benefit the United States, indicating areas for current policy emphasis. Together, the two papers provide a timely and important examination of the current state and the likely future of United States military space.
