  • This objective of this study is an effort to predict atomic oxygen (ATOX) erosion as ot affects coating material(s) of LEO satellite's solar array by implementing the 'real ram direction accumulation method'. We observed the difference of ATOX Fluence between the previous 'Maximum worst case estimation method' and 'Real ram direction accumulation method' and we plan to implement these findings for the purpose of evaluating the level of compliance for design submitted by solar array suppliers. We used the SPENVIS(Space Environment Information System) served by ESA based on assumption orbit information, and applied the satellite orbit calculation software for calculating the ATOX Flux crushed solar array in real orbit surface.
