Abstract
More than 10 years of on-orbit UC1864 SEU data are compared with typical upset rate calculation methodologies and GCR environments. Results suggest that the most common calculation methods overestimate upset rates by at least 2×. Mitigation techniques are also verified via direct in orbit observations.
