  • This paper describes an MRE(Monitoring and Reconfiguration Electronics) which is in charge of SCU(Spacecraft Computer Unit) hardware failure monitoring as well as of protecting the satellite against system failures. To achieve it, MRE is designed that it is an independent function with respect to the rest of the SCU, that is, care is taken into account in order to minimize the interface(the failure propagation) between the MRE and the other SCU functions.

  • In this paper, we design COMS system bus that the 1553 Data Bus is able to link all the units of the satellite managed by the SCU using one Prime Data Bus and on Redundant Data Bus. Also we analyze MIL-STD-1553B bus load and relevant exchange memory budgets in system bus of the COMS satellite. This data is used in the satellite mission and software design by system engineer.
