Abstract

Inexpensive commodity microcontrollers are extremely attractive for offloading low-level, real-time computations from high-performance spacecraft computers due to their high functional density and low power, but they have not been widely used because of their low radiation tolerance. This paper presents a fault-tolerant microcontroller configuration specifically designed to tolerate space-radiation effects that be used for embedded real-time control in spacecraft. The requirements and fault-environment are examined, then an architecture is presented. An experimental testbed is described along with fault-insertion test results.
