Paper Abstract

STSAT3, a ~150 kg micro satellite, is the third experimental microsatellite of the STSAT series designated in the Long- Term Plan for Korea's Space Development by the Ministry of Education, Science and Technology of Korea. STSAT3 is being developed for launch into a sun-synchronous orbit of 700 km altitude by the end of 2010. A compact imaging spectrometer (COMIS) is a secondary payload of STSAT3 that will be employed for environmental monitoring, mainly over the Korean peninsula. COMIS was inspired by the success of CHRIS, a previous PROBA payload. The chief function of COMIS is to image the Earth's surface with ground sampling distances of 30m or less at 18~62 spectral bands (4.0~1.05μm) for nadir observation at 700km altitude. COMIS, as its name implies, is very compact in volume, mass, and power. The total mass including optics, housing, and electronics is about 4.3kg and the average power per orbit is less than 5 watt. This paper reports on the prototype development of COMIS.
