Abstract
A detailed analysis of the error injection defined in the DPU-ASW error handling strategy [RD-1] in function of the error criticality using the PUS service 5 classification is done. As well as a classification according to the source of the error e.g. operative system, DPU-ASW, NISP commands, or hardware failure; and an analysis of the frequency of the occurrences in the worst-case scenario is given. This analysis does not consider the multiplicity of a repeated error (within one second) which is handled internally according to [RD-1]; in this case a single error will be injected in the 1553 interface, and all the considerations described here are applicable.
