Functional safety and reliability of TUMnanoSAT satellite on-board computer software

Abstract

The TUM National Space Technologies Center team was selected by the Japan Aerospace Agency (JAXA) and the United Nations Office for Outer Space Affairs (UNOOSA) for the fourth round of the KiboCUBE Program for the launch of the TUMnanoSAT nanosatellite from the International Space Station (ISS) in 2020, with the help of the japanese experimental KiboCUBE module. The National Space Technologies Center of TUM projected the family of TUMnanoSAT’s nanosatellites, according to the international CubeSat standard. In the 2019 year, NCST participated in the fourth round of the KiboCUBE Program with the nanosatellite project from the “TUMnanoSAT” family. The harsh space environment with high levels of radiation and large temperature variations (even on low earth orbits) imposes the implementation of measures and techniques to achieve high level of satellite systems reliability over its full lifetime.
