Abstract :
The use of microsatellites for remote sensing missions is becoming more attractive. The cost-reliability issue is still a constraint. In this work we present a methodology for the development of Fault Tolerant Space Systems (FTSS) focusing on the On Board Data Handling (OBDH) system for microsatellite´s remote sensing payloads with COTS components. The methodology presented is based on Fault Tolerance Techniques applied to Field Programmable Gate Arrays. The proposed methodology ends with a guideline for simulating the system reliability, providing statistics to support decisions regarding the necessary techniques to be implemented.
