VICENTE-VIVAS, Esaú  y  GARCIA-NOCETTI, Fabián. Fault Tolerant Computing Applied to Automatic Maintenance of the Satex Microsatellite. Inf. tecnol. [online]. 2006, vol.17, n.1, pp.61-68. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000100008.

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.
