A low-power GNSS payload board for precise orbit determination onboard the ARIS SAGE microgravity nanosatellite: Project within the scope of the MSc Geomatics, Spring Semester 2023

Abstract

The mission SAGE by ARIS (Akademische Raumfahrt Initiative Schweiz) examines the aging of human cells in milligravity conditions. Therefore, a low-power GNSS payload board for positioning, precise orbit determination and attitude determination is foreseen to complement the satellite's equipment. This paper defines fundamental technical specifications such as the necessary configurations of the GNSS receivers and describes the implementation to read and parse the received messages. Furthermore, it presents an experiment to analyse the noise behaviour of the received signals.
