Data Stream Superposition Test Method of Satellite Control Subsystem

In order to meet the challenges of more and more complex requirements, shorter development cycle and lower cost, a data stream superposition test method for satellite control subsystem is proposed in this paper. This method combines the characteristics and test requirements of the product, analyzes the data flow of the sensor, controller and actuator, decouples the product performance test from the subsystem test, superposes the measured data of the sensor and simulation data in the attitude and orbit control computer, and sends down the control value for the ground dynamics simulation calculation. Using this method, the composition of test equipment is simplified, the test preparation time is shortened, the test preparation requirements are reduced, and the product performance evaluation means are enriched.
