Performance
Scientific paper
Over the past years, several studies have concluded on the capability to perform high optical resolution missions based on microsatellites. One of the most interesting outcomes is the evidence that the sub-metric ground resolution performance, usually deemed accessible to the only large spacecraft, is actually achievable with a 120kg microsatellite. This allows new affordable system concepts for earth observation. This paper describes the design and performance of such a microsatellite: the optical imaging instrument makes use of an all ceramic SiC telescope. The platform is derived from the Myriade line-of-product developed by CNES. Considering clusters or constellation of microsatellites, open the way to new fast services with drastically reduced access times and revisit periods. It would however be erroneous to conclude that microsatellites could replace highly performing observation spacecraft, instead they shall be regarded as a mean to provide new services where a minimum access time and revisit period are key.
