The resolution of conventional space telescopes is limited by the size of their aperture. High resolution telescopes must have large aperture primary mirrors - heavy, expensive and costly to deliver to orbit. In contrast, micro-satellites are small, relatively inexpensive, and are often "hitch-hiked" with other payload to orbit. However, the size of micro-satellites limits them to small aperture optics. By combining multiple images from a suitably-designed telescope with several small mirrors and digitally post-processing the combined image, it is possible to obtain higher resolution. The optical layout and the digital post-synthesis for these proposed micro-satellite telescopes are presented and analyzed.
