Design and Implementation of Intelligent Spaceborne Test Unit

As the satellite operates in orbit, it is affected by the space environment, and it is difficult to always ensure its normal operation. Through the satellite in-orbit test, the satellite's in-orbit operating status can be monitored, so that the satellite can be managed and remotely controlled to ensure the normal operation in time. This work describes a general-purpose intelligent spaceborne test unit for satellite integrated electronic systems. The designed unit is divided into three parts that are data acquisition unit, information processing unit and data storage unit. The data acquisition unit has multiple communication interfaces which are used to collect state data on the satellite, and the information processing unit runs the fault prediction algorithms to monitor and predict the state of the satellite, and deliver the results and the important state parameters into the data storage unit. After experimental verification, the intelligent spaceborne test unit has communication interfaces commonly used on satellites, and has the ability to collect satellite status data. It can also accelerate the execution of LSTM fault prediction algorithms and quickly store the analysis results. The intelligent test unit is efficient and reliable, which supports rapid extended development on this platform. It is capable of carrying out satellite fault monitoring and can be used for the on-board health management system in future.
