The introduction of commercial off-the-shelf (COTS) technology into micro-nano satellite design becomes a development trend. In view of low cost,miniaturization and high reliable application development needs of micro-nano satellite electronic system,the design features of micro-nano satellite’s on-board computer (OBC) are compared both at home and abroad. A low cost and high reliable micro-nano universal OBC architecture based on the triple modular redundancy (TMR) is put forward. Using standard interface,layered software and TMR,hardware watchdog design,a kind of general,stable and reliable electronic system is designed and its good application prospect in the scientific experiment and new technologies demonstration,distributed space systems and military is discussed.
