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.

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.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the eight years from 1995 to 2003, over 890 commercial communications satellites comprising 34 new system constellations will be placed into service orbiting our planet. Many recent studies of the future United States military have identified satellite communications as key to the of the future force. The military's requirement for command and control on the move (C2OTM) and its penchant for often deploying to areas where little or no infrastructure exists further validate this satellite communication requirement. Although the military has its own satellite communications systems in use now and planned for the future, those systems have relatively low throughput and therefore do not satisfy the gross future requirements. As military budgets shrink and military constellations wear out without our ability to replace but a very few justified hardened systems, DoD must acquire the best possible mix of satellite communications support for the warfighter via commercial means. The three keys to military success for the force after next in this dual use area of technology will be: (1) knowledge of our own requirements, (2) knowledge of the technology's limitations, and (3) close cooperation with industry to insure our service specific requirements are met.

Available in PDF, EPUB and Kindle. Book excerpt: "DOD depends on commercial SATCOM to support a variety of critical mission needs, from unmanned aerial vehicles and intelligence to voice and data for military personnel. In fiscal year 2011, the most recent information available, DOD spent over $1 billion leasing commercial SATCOM. In prior work, GAO found that some major DOD users of commercial satellite bandwidth were dissatisfied with DISA's acquisition process seeing it as too costly and lengthy. These users also indicated that the contracts used were too inflexible. The Senate Armed Services Committee's report accompanying the National Defense Authorization Act for Fiscal Year 2014 included a provision for DOD to report on the future mix of military and commercial SATCOM and for GAO to review DOD's report, issued in August 2014. This report (1) assesses the extent to which DOD efficiently procures bandwidth, (2) analyzes the extent to which DOD has identified its future SATCOM requirements using DOD and commercial satellite services, as well as how those requirements will be met, and (3) identifies the steps DOD is taking to improve its procurements of commercial SATCOM. To conduct this work, GAO reviewed DOD's reports, DOD SATCOM procurement guidance, prior GAO reports, and interviewed DOD officials"--Preliminary page.

Available in PDF, EPUB and Kindle. Book excerpt: Since the Gulf War of 1991, United States military satellite communication (SATCOM) bandwidth demand has increased dramatically, as evidenced by recent usage rates in Operation Enduring Freedom and Operation Iraqi Freedom. The Department of Defense (DOD) has increasingly relied on commercial vendors to meet this demand. With an open-ended Global War on Terror and heavy reliance on bandwidth-intensive operations (such as unmanned aerial vehicle feeds), the demand is projected to continue increasing at huge levels. It is unlikely that reliance on commercial SATCOM will decrease, despite numerous planned military SATCOM assets launching over the next ten years. While commercial SATCOM is essential to most military operations and provides many advantages, its pervasive use also raises concerns related to security, cost, and survivability. This thesis analyzes the balance between Cod use of commercial SATCOM versus military SATCOM. It surveys historical and current military usage of Cod and commercial SATCOM, evaluates current predictions for military use of commercial SATCOM, and describes measures of effectiveness that can be used to evaluate the various SATCOM options. In culmination, this thesis defines what constitutes an appropriate balance of military and commercial SATCOM usage using cost, technical, and policy compliance measures of effectiveness. The measures of effectiveness lead to a recommendation of a more deliberate, less ad hoc use of commercial SATCOM for the vast majority of military SATCOM needs.
