Abstract

To characterize galactic cosmic ray (GCR) in low earth orbit (LEO) near the equator (NEqO), we considered GCR fluxes and their single event upset (SEU) rates and absorbed dose in a chosen material. Data on fluxes and SEU rates are estimated with the help of an online tool called Space Environment Information System (SPENVIS) while absorbed dose is estimated using CREME96 model. Comparison with trapped protons is also done. It is found that GCR dose is less than trapped protons dose but GCR particles can still contribute to the damages in spacecraft especially due to the presence of heavy ions.
