Especificacao e Analise de Mecanismos de Deteccao de Erros Para O Padrao INPE de Supervisao de Bordo (Specification and Analysis of Error Detection Methods for the INPE Standard for on-Board Supervision)

摘要

Error detection techniques and mechanisms to be implemented in the processing units specified by the INPE's Standard for On-board Supervision (PISB), responsible for the on-board supervision tasks in the MECB (Brazilian Complete Space Mission) satellites are presented and analyzed. The described techniques and mechanisms are closely related to each functional subunit that compounds the processing units. Self-test procedures and error detection between the two approaches for the error detection function are analyzed. In addition, the problem of test realization in the functional subunits with the use of an external test equipment is considered. Specific test procedures aiming to achieve this goal are proposed for each basic functional subunit.
