The primary SBSS contractor, Boeing, characterizes some orbiting space objects as, "Potential future threats to the United States' space assets."〔(【引用サイトリンク】title=Boeing and Ball Aerospace Achieve New Milestone for SBSS Program )〕 The SBSS development work is being conducted in coordination with the Space Situational Awareness Group in the Space Superiority Systems Wing of the United States Air Force. The commander of the Space Situational Awareness Group believes the SBSS satellite operations center, "Will transform Space Situational Awareness by providing a gateway to a responsive, taskable sensor. This capability is key to enabling the event-driven operations concept of the future."〔(【引用サイトリンク】title=Boeing Completes Hardware Installation for SBSS Satellite Operations Center )〕 == Pathfinder satellite == The first "pathfinder" satellite of the SBSS system was successfully placed into orbit on board a Minotaur IV rocket on September 25, 2010.〔(【引用サイトリンク】title=Minotaur IV & V )〕〔(【引用サイトリンク】title=Vandenberg launches Minotaur IV )〕 Originally, the launch was scheduled for December 2008 but was rescheduled for Spring of 2009,〔(【引用サイトリンク】title=Boeing SBSS System Progressing Toward 1st Launch )〕 and again delayed until 22 Oct 2009. The launch delays were caused by problems with the booster, and not the satellite itself. A launch expected for July 8, 2010〔() Boeing Team Ships First SBSS Spacecraft To Launch Site〕 was also postponed.〔http://news.yahoo.com/s/ap/20100706/ap_on_hi_te/us_space_traffic_cam_delay〕 The program cost $823 million, including satellite, payload, launch, and ground support. (The satellite and payload contracts to Ball Aerospace are approximately 40% of the total.) It is designed to examine every spacecraft in geosynchronous orbit at least once a day.〔 The SBSS pathfinder satellite has a 30 cm telescope on a two axis gimbal with a 2.4 megapixel image sensor and has a projected mission duration of five and a half years.〔http://www.ballaerospace.com/file/media/SBSS%2006_10.pdf〕 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「Space Based Space Surveillance」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
