Run-time control design of micro-satellite OBC based on reconfigurable architecture

To address the issues of on-board computer (OBC) design by traditional method for micro-satellite, an advanced OBC based on reconfigurable architecture was presented, and its run-time control scheduling was designed. This reconfigurable OBC could implement supervision which ensured the running status, function reconfiguration which switched its current control modes, restoring reconfiguration through searching and shielding the problem region, and software/hardware upgrading reconfiguration which could accomplish in orbit. Semi-physical simulation platform composed with OBC prototype board, DSpace simulator and laboratory terminal was established, then the performance and run-time control scheduling of this OBC was proved in the platform.
