摘要

Surrey Satellite Technology (SSTL) has pioneered the development of successful low cost micro-satellites that demonstrate highly capable Earth Observation sensors. This paper describes the in-orbit data produced by several Surrey satellites including the UoSAT-12 mini-satellite launched in April 1999 which carries a 32-m ground sampling distance (gsd) multispectral imager and a 10-m panchromatic camera. In addition, data is presented from the micro-satellites Tiungsat-1 and Tsinghua-1 launched in 2000, and AlSat-1 launched in November 2002. AlSat-1 carries a unique imaging system designed as part of the innovative Disaster Monitoring Constellation (DMC). The multispectral 32-m gsd imager has a 600-km swath width so that five satellites in the constellation can provide daily imaging worldwide. The paper also describes the latest advances in imaging using two new low cost small satellites being built at Surrey. The commercial RapidEye constellation is designed to provide daily imaging at 6.5-m gsd over Europe for precision farming applications. At a higher resolution, TopSat is a pilot mission for the UK Ministry of Defense carrying a 2.5-m gsd panchromatic camera on a highly agile micro-satellite.
