Radiation characteristics and SEU rates in NEqO environment using SPENVIS

RazakSat1 was launched at Near Equatorial Orbit (NEqO) where Trapped Protons/Electrons (TP/TE) and Galactic Cosmic Rays (GCR) has intensive effect on satellite's memory like SRAM based FPGA. Due to this devastating effect, it is important to investigate the radiation environment of the orbit to...
