Description
CRRES on-orbit experiments frequently required reconfiguration to meet test objectives. Our analysis of the environmental conditions, during the time of these satellite anomalies, indicated a probable environmental cause. We examined possible contributing factors; such as geomagnetic storms, proton enhancements, and transient, high-energy electron fluxes; to develop experiment reconfiguration thresholds. This paper specifies each threshold f s accuracy as an alert or warning criteria and indicates the time-dependence of satellite vulnerability, particularly after the major solar flare of 22 March 1991. We further suggest implications for other similarly radiation hardened satellites or satellite subsystems.
