Abstract

In this paper, a development approach is proposed for micro-camera systems that are dedicated to constellation operations of satellites. It is to take a regular practice and design the system based on traditional, professional optical layouts rather than simplifying configuration. LIBERO-1 and LIBERO-2 are the cameras under development to study whether the approach is feasible. LIBERO-1 is designed to have better than 1-m resolution in panchromatic spectral channel at the altitude of 500 km. It can support up to 6 multispectral channels and 12000 active pixels in swathwidth. The dimension is estimated to be within 20 cm x 20 cm x 30 cm, which is almost half the length of 1-m resolution cameras available in market. LIBERO-2 has better than 2-m resolution at 500 km altitude. It can also support up to 6 multispectral channels and 8000 active pixels in swathwidth. LIBERO-2 has a similar size to star sensors so that its dimension is 10 cm x 10 cm x 20 cm.
