The evaluation of the on-board computer architecture for TUMnanoSAT series of nanosatellites for carrying out missions

Abstract

In this paper, a brief overview of the nanosatellite on-board computer (OBC) functions will be described. The main advantages and disadvantages of the most common OBC architecture will be explained. A set of three different architecture variants for TUMnanoSAT series of CubeSat nanosatellites is proposed and described. A feature comparison is performed in order to highlight the improvements and advantages of the proposed on-board computer architecture designs over traditional CubeSat OBC architectures.
