DubaiSat-1 is a remote sensing Earth observation satellite built by the ''Emirates Institution for Advanced Science and Technology (EIAST)'' under an agreement with ''Satrec Initiative'', a satellite manufacturing company in South Korea. The earth observation satellite was designed and developed by ''Satrec Initiative'', with participation from EIAST engineers. DubaiSat-1 was launched on July 29, 2009 into a 680 km altitude sun-synchronous polar orbit from the Baikonur launch site in Kazakhstan, along with several other satellites on board the Dnepr launch vehicle.〔(【引用サイトリンク】 title=DubaiSat 1 )〕 ==Overview== DubaiSat-1 observes the earth at a Low Earth orbit (LEO) and generates high-resolution optical images at 2.5m in panchromatic and at 5m in multispectral bands. These images provide decision makers in the UAE as well as EIAST clients with a valuable tool for a wide range of applications including infrastructure development, urban planning, and environment monitoring and protection. DubaiSat-1 images are also useful for promoting geosciences and remote sensing research in the region, and for supporting different scientific disciplines in private and academic sectors.〔(【引用サイトリンク】 title=DubaiSat-1 Space Segment )〕 For example, DubaiSat-1 images have been used, to monitor progress on the Dubai World Megaproject, Palm Islands, and the Al Maktoum International Airport. The United Nations also used DubaiSat-1 images to monitor relief efforts following the 2011 Tōhoku earthquake and tsunami in Japan. The satellite accommodates two main payloads. The primary payload is the ''Dubai Medium Aperture Camera (DMAC)'', and the secondary and experimental payload, the ''Space Radiation Monitor (SRM)''.〔 The DMAC system is pushbroom imaging system with one panchromatic and four multi-spectral imaging channels. It also consists of an ''Electro-Optical Subsystem'' and the ''Payload Management Subsystem''. The Electro-Optical Subsystem has a telescope, a focal plane assembly, and a Signal Processing Module. The Payload Management Subsystem consists of the ''Thermal & Power Module'' and the ''Mass storage & Control Module''.〔 The ''Space Radiation Monitor'', the secondary and experimental payload, is capable of measuring the total ionizing dose from the charged particles at the orbits of satellites. The instrument utilizes four ''p-type Metal-Oxide-Semiconductor Field Effects Transistors (MOSFETs)''. These devices measure the current-voltage characteristics of the satellite. Subsequent analysis will allow measurements of the amount of cumulative ionizing dose, and of the total ionizing dose of the devices.〔 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「DubaiSat-1」の詳細全文を読む スポンサード リンク
