Resumen:
This work presents the development of a fault-tolerant computer architecture with enough capability to apply both remote and automatic maintenance to the Satex microsatellite flight computer (MES). Small satellites, such as MES, have undergone a tendency to increase in value-added and cost of their experiments, which justify the use of fault-tolerant and long lived instrumentation, especially if this can be obtained at affordable cost. The proposed fault-tolerant computer architecture employs all the satellite processing resources to collectively perform different tasks such as computer diagnosis, fault detection, as well as architecture reconfiguration in case of faults. © 2006 Centro de Información Tecnológica.
