Orbital Radiation Study for Inclined Circular Trajectories,

Abstract

A comprehensive study was conducted to determine the space radiation environment of a series of high inclination geocentric orbits for a mission duration of five years. Following the precedent established, the external (surface incident) charged particle radiation, predicted for the satellite was determined by orbital flux integration for six independent trajectories. The latest standard models of the environment were used in the calculations. Magnetic field definitions for the six nominal circular trajectories were obtained from a current field model. Spatial and temporal variations or conditions affecting the static environment models were considered and accounted for, wherever possible. Finally, limited shielding and dose evaluations were performed for simple infinite slab and spherical geometries. Results, given in graphical and tabular form, are analyzed.
