Comparison of Ax8 and Ax9 Trapped Environment Models for Various Orbits
Abstract
This report compares the Ax8 mean environment with the Ax9 95 percent confidence environment for a range of potential mission orbits. It is shown that a commonly held rule of thumb that Ax9 (95 percent) is roughly 2x the Ax8 mean level is not valid except for GEO behind a typical range of spacecraft shielding. All other missions should carefully evaluate the environment from the Ax9 model instead of relying on an arbitrary scaling from past experiences.
