The Naval Space Command (NSC) was a military command of the United States Navy. It was headquartered at Dahlgren, Va., and began operations Oct. 1, 1983. Naval Space Command used the medium of space and its potential to provide essential information and capabilities to shore and afloat naval forces by a variety of means: *Operating surveillance, navigation, communication, environmental, and information systems; *Advocating naval warfighting requirements in the joint arena; and *Advising, supporting, and assisting the naval services through training, and by developing space plans, programs, policies, concepts, and doctrine. The command was merged into Naval Network and Space Operations Command, itself part of Naval Network Warfare Command, about July 2002.〔United States Navy, (), accessed February 2012〕 ==Overview== Naval Space Command's headquarters staff and operational element numbers approximately 350 Navy military and civilian personnel. Their component commands include the Naval Satellite Operations Center and the Fleet Surveillance Support Command. Naval Space Command, a component of USSPACECOM, operates assigned space systems to provide surveillance and warning, and provides spacecraft telemetry and on-orbit engineering support. In addition, Naval Space Command serves as the Alternate Space Control Center () for USSPACECOM's primary centers located at Cheyenne Mountain AS. ASCC missions include operational direction of the entire global space surveillance network (SSN) for commander in chief, USSPACECOM (USCINCSPACE). The ASCC also detects, tracks, identifies, and catalogs all man-made objects in space and provides position information on these objects to about 1,000 customers. In addition, ASCC is charged with monitoring the space environment and informing owners and operators of U.S. and allied space systems of potential threats to their assets by continuous liaison with the systems' operations centers. The heartbeat of Naval Space Command revolves around providing space support to day-to-day operations of the Fleet and Fleet Marine Forces worldwide, whether for routine deployments, exercises, or actions in response to a crisis situation. This space support to terrestrial and naval forces can be categorized across a broad spectrum of activities that encompass communications, surveillance and indication, and warning, intelligence, navigation, and remote sensing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Naval Space Command」の詳細全文を読む スポンサード リンク
