Abstract
Single event upset (SEU) rates in orbit have been measured for the ROS AT satellite Wide Field Camera's (WFC) Command and Data Handling Syste m (CDHS) memory. The WFC was launched as part of the German/UK/USA ROS AT satellite mission on the 1st of June 1990. In over 600 days of oper ation 40 SEUs were detected. Most appear to be associated with the Sou th Atlantic Anomaly. Agreement between predicted and measured rates is discussed. Problems associated with such analysis are highlighted inc luding the need for more relevant test data for electronic devices use d in orbit. Detection technique is described along with several featur es of the WFC operations, CDHS software and construction which directl y relate to SEUs. No incidences of multiple bit upsets were detected.
