COTS (Commercial Off The Shelf) components have the advantages of high performance, low cost, easy acquirability, and short lead times. However, when used in space applications, these components encounter environmental interference. A computer system is designed using COTS components, with an ARM processor as the data processing core and employing a dual-redundant structure. It implements key technologies such as hardware fault detection and correction based on field-programmable gate arrays, watchdog technology, and power supply with latch processing. The system subjects to flight verification in a near-earth orbit. By comprehensively analyzing the in-orbit test data, the functions and application techniques of fault-tolerant technologies for COTS components are elucidated, offering valuable insights for engineering practice.

A computer system is designed using COTS components, with an ARM processor as the data processing core and employing a dual-redundant structure. It implements key technologies such as hardware fault detection and correction based on field-programmable gate arrays, watchdog technology, and power supply with latch processing. The system subjects to flight verification in a near-earth orbit. By comprehensively analyzing the in-orbit test data, the functions and application techniques of fault-tolerant technologies for COTS components are elucidated, offering valuable insights for engineering practice.
