Upsets in the Freja Magnetic Field Experiment

Abstract

Several methods exist for estimating single event and proton upset rates based on ground test data. The accuracy of these methods is crucial to successfully designing spacecraft systems. This paper presents flight upset data from static RAMS used in the Freja Magnetic Field Experiment and compares the flight data to estimates generated by commonly used methods. The flight data is also used to test common assumptions about the variability of the orbital environment.
