Research on Spacecraft Rapid Test Technology Based on Built-in Self-test

Traditional spacecraft design focuses on function implementation and lacks the consideration of testability. Spacecraft integrated test relies on telemetry and command. The test cycle is long, the test efficiency is low and the cost is high. The traditional test mode can't adapt well to the needs of spacecraft batch manufacture. Through Model-based BIT technology, civil automobiles and airplanes have established on-board diagnosis system and on-board maintenance system, which greatly improves the ability of rapid maintenance and functional reconfiguration. Referring to the civil rapid electrical inspection technology, the spacecraft self-test models are designed from two aspects of behavior model and structure model, so as to enhance the capability of spacecraft rapid inspection.
