NANOsky I is a highly miniaturized nanoscale platform with fault tolerant features as would be expected in high end systems. SEE immunity, innovative error mitigation techniques, sophisticated three-level FDIR policy, redundancy on all critical functions and thoughtful component selection ensure robustness, high reliability and availability of the platform. On-board data handling functionality exploits the advantages of the reliable hot redundant CAN networking with built-in error detection mechanisms and a ruggedized and fail-safe harness to reduce the overall system complexity and to extend the miniaturization aspect. The additional high speed LVDS links can easily cope with payloads producing large amount of data. Small in scale while big on features are the key advantages addressing the new horizons of the emerging space market.
