Micro-satellite series of platforms
The micro/nano-series computer, based on Chinese SM1757 anti radiation processor chip, is a nano-class integrated product geared to the needs of space reliability. By adopting the design concept of whole satellite “integration”, the product integrates the housekeeping, attitude control, S-band spread spectrum transponder, GPS/Beidou two-mode navigation. It is composed by 100 × 100mm standard size, and can be spread and customized according to user’s requirements.
