Abstract

The goal of this paper is to describe main features and technical solution of projected microcontroller control unit for CubeSAT picosatellite. The first part is focused on the hardware solution and the design of prototype board is discussed. The extensive emphasis will be put on the solution of forced switching of two running microprocessors (HW watchdog for master and backup microprocessors). The second part of this paper deals with software solution and shows proposed reliability models for this system.
