On-orbit alignment and wavefront compensation of segmented aperture telescope using adaptive optics

For small satellite remote sensing missions, a large aperture telescope more than 400mm is required to realize less than 1m GSD observations. However, it is difficult or expensive to realize the large aperture telescope using monolithic primary mirror with high surface accuracy. A segmented mirror telescope should be studied especially for small satellite missions. We describe the conceptual design of the optical system that involve the segmented primary mirror and adaptive optics system, then we show numerical simulation results of the optical performance.
