Digital Fault Mode Modeling for Spacecraft Engineering System

Based on the goal of digital spacecraft construction, guided by the task requirements, the spacecraft system engineering method based on model is used to carry out the construction and application of multidisciplinary digital spacecraft covering various levels from system to subsystem to single machine,providing strong support for ensuring the success of operational tasks and improving the efficiency of in orbit spacecraft operations. Based on the topology structure of the spacecraft engineering system, overall modeling digital spacecraft engineering system method is conducted to support the spacecraft engineering practice, and form a mode of spacecraft development system in the digital era. The fault handling plan based on the digital spacecraft system model is validated to assist in spacecraft fault diagnosis and recovery, strengthen the digital control ability of the technical state of spacecraft products.
