The Disaster Monitoring Constellation for International Imaging (DMCii) consists of a number of remote sensing satellites constructed by Surrey Satellite Technology Ltd (SSTL) and operated for the Algerian, Nigerian, Turkish, British and Chinese governments by DMC International Imaging. The DMC provides emergency Earth imaging for disaster relief under the International Charter for Space and Major Disasters, which the DMC formally joined in November 2005. Other DMC Earth imagery is used for a variety of civil applications by a variety of governments. Spare available imaging capacity is sold under contract. The DMC provides far larger areas of imagery than, but at comparable resolution to, established government imaging satellites such as Landsat. DMC imagery was deliberately designed to be comparable to Landsat imagery, in order to leverage the expertise and software of the large established remote sensing community used to working with Landsat images. Imagery can be provided far more rapidly from the DMC than from Landsat, thanks to having multiple similar satellites in orbit ready to cross over a point of interest, and the larger images produced. This brings the responsiveness that is needed for emergencies and for disaster support, with images provided across the Internet from the responsive satellite and a member country's ground station within a day or less of a request being made. The DMC has monitored the effects and aftermath of the Indian Ocean Tsunami (December 2004), Hurricane Katrina (August 2005), and many other floods, fires and disasters. The individual DMC satellites are: ==First Generation== * AlSAT-1 (Algeria), launched November 2002, which completed its mission in August 2010.〔J Cooksley, A da Silva Curiel, P Stephens, L Boland, S Jason, W Sun, M Sweeting, ("ALSAT-1 First Year In Orbit" ), 17th AIAA / USU Conference on Small Satellites, 2003〕〔(Algeria’s first satellite mission completed ), Robin Wolstenholme, SSTL space blog, 26 August 2010.〕 * BilSAT (Turkey), launched September 2003, which completed its mission in August 2006 due to failed battery cells 〔(BilSAT News ), retrieved 23 July 2007.〕 * NigeriaSAT-1 (Nigeria), launched September 2003, completed mission October 2012.〔(NigeriaSAT-1 reaches end of long life ), SSTL space blog, 29 October 2012.〕 * UK-DMC (United Kingdom), launched September 2003, completed mission November 2011.〔(UK-DMC-1 to take well-earned retirement ), SSTL space blog, 25 November 2011.〕 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「Disaster Monitoring Constellation」の詳細全文を読む スポンサード リンク
