Shielding design considering commercial parts for LEO mission satellite using SPENVIS software

The space radiation environment includes trapped protons and electrons, solar protons, galactic cosmic radiation, and neutrons, which can lead to electronic satellite malfunctions. Radiation damage has destructive effects on the electronic components of satellites. As a result of economic reasons and the presence of various limitations, the utilization of commercial components has become common in short-term and low-altitude missions. The most efficient method of protection against radiation is the use of shields. The purpose of this study is to investigate the optimal shielding in a ۳-year mission in LEO orbit by considering the radiation resistance of commercial parts using SPENVIS software, SHIELDOSE code, and MULASSIS software. The result of SHIELDOSE, MULASSIS calculations is that the amount of thickness of different materials for the radiation tolerance of commercial parts does not vary significantly in condensation thickness. Furthermore, there is no need for complex protection and you can utilize the usual protections. A comparison of the calculations obtained from MULASSIS and SHILEDOSE to deliver the dose into the silicon target indicates that the values are very similar and if there is a limitation in each of the capabilities of either MULASSIS and SHILEDOSE, another can be utilized as a substitute software.
