Dependability Issues of INPE's ESA/CCSDS Telecommand/Telemetry Subsystem

Abstract

This paper introduces and discusses dependability features of a Telecomm and and Telemetry subsystem designed under a Brazilian Space Program contract. The whole subsystem has been developed in a hardware description language (HDL), targeting anti-fuse programmable once FPGA devices. The discussed features include device redundancy, at hardware level, and several adopted strategies at the HDL level.
