Abstract

The CubeSat standard has inspired a lot of engineers, researchers and space industries because of its simplicity and its previous success stories. There are various applications of CubeSats such as remote sensing, telecommunications, earth observations as well as interplanetary science missions. In recent times, newer telecommunication technologies are developed and they are needed to be tested in space conditions. Since it is a difficult task to simulate the space environment, CubeSats are used as a test bed for the newer technologies. In order to use the Microwave photonic technology in larger satellites, the degradation of these components due to radiation are needed to be studied. Inspired by the simplicity of CubeSat's, Thales Alenia Space proposed a project CubeSat NIMPH (Nanosatellite to Investigate Microwave Photonics) in collaboration with the CNES, ISAE-SUPAERO and other French Universities. This research presents the process of developing a physical solution to the critical aspects of radiation in the CubeSat NIMPH. This work also shows the accumulated radiation dose through computational methods like Sector analysis and Monte-Carlo methods using TRAD FASTRAD software. Results of the analysis provide the maximum dose level and the need for radiation shield for the platform. Based on the detailed review of results, the overall configuration is chosen and the Erbium Doped Fiber Amplier (EDFA) is made sure that it reaches a cumulative dose of 20 Krad.
