Effects of radiation on digital architectures: one year results from a satellite experiment

Abstract

Twenty-four experiments on-board a scientific satellite, successfully launched by Naval Research Laboratories, are operating in a high radiation environment since November 1997. Two of these experiments, designed by TIMA in collaboration with CNES (French Space Agency) were programmed to provide evidences of Artificial Neural Network intrinsic fault tolerance properties. This paper presents conclusions issued of the analysis of more than one year telemetred data.
