The technology of microsatellite is an important achievement of high integration of space technology, electronic technology, computer technology, optics technology and remote sensing technology, many countries, especially west countries are interested in its development and application. The Space Center of Surrey University of British has developed and designed more than 20 microsatellites for more than 10 countries. Some institutes of our country have a plan of cooperation with Surrey University in absorbing microsatellite technology. Through analyzing the imagery qualities and features of the data that acquired from microsatellite,authors consider it will have good prospects in global disaster and environmental monitoring, agricultural evaluation and resource survey in the near future. In China, developing itself microsatellite technology will have a strong promotion for its space remote sensing application in social sustainable development.
