Abstract :
Sumbandilasat´s Commercial-Off-The-Shelf based On-Board-Computer´s radiation performance is analyzed. Total dose simulation and test results of major components are presented. Single Event Effect rates from simulations and in-orbit data are compared. The feasibility of this COTS based design approach for small satellites in Low Earth Orbits is proven.
