Space Radiation Environments for Parts Selection/Test Considerations in Typical Satellite Orbits

摘要

This document contains the results of a space radiation environment study that can be the basis for parts selection and radiation tradeoff architectures for several typical spacecraft orbits used (or contemplated for use) by DoD and other government agencies. The radiation levels calculated can be used to select and test components for many spaceflight systems and subsystems. This report provides the first step in developing a comprehensive test program plan to examine all deleterious space effects that could degrade or disrupt sensor systems from meeting their mission goals regarding both performance and lifetime. The radiation levels recommended in this report represent a reasonable near worst case environment for all of near-Earth space out to geosynchronous altitudes. The recommended levels are such as to have low risk for mission lifetime without providing an overly cautious approach that could reduce program flexibility in the selection of components and inflate costs beyond program budget constraints.
