The invention discloses a digital closed-loop optical fiber gyroscope full-loop detection and simulation test system which comprises an optical system module, a pre-amplification module, a digital processing module, a feedback module, a communication module and a ground detection and simulation test system. Under a condition of no turntable, the digital closed-loop optical fiber gyroscope full-loop detection and simulation test system can realize full-loop detection on an optical fiber gyroscope; under a condition of no angle vibration table and sudden stop table, a stand-alone bandwidth test on the optical fiber gyroscope can be implemented; the self-condition limitation of the conventional mechanical equipment is avoided in a test process; under a condition that any auxiliary ground detection circuit is not added, a dynamic simulation function of a branch system can be realized, and parameter limitation caused by auxiliary circuits is avoided; complicated dynamic simulation is implemented. According to the digital closed-loop optical fiber gyroscope full-loop detection and simulation test system, the power consumption and weight of a product are reduced, and the cost is lowered; minimized and low-cost design of the product is realized.

technical field [0001] The invention belongs to the technical field of inertial attitude sensor systems, and relates to a digital closed-loop fiber optic gyroscope full-loop detection and simulation test system. Background technique [0002] In recent years, due to the prosperity of the micro-satellite market, the research on low-cost and miniaturized inertial attitude sensors has developed rapidly. In order to perform ground physical simulation for satellite products, all stand-alone machines must have a ground detection function, so it is necessary to increase the auxiliary circuit to realize the ground detection function, which increases the power consumption, size and weight of the product. [0003] As an important frequency characteristic, bandwidth test is an important content of gyroscope performance test. The traditional method is to use mechanical equipment such as sudden stop table and angular vibration table to obtain the frequency response curve, and then calcul...
