Description

technical field [0001] The invention belongs to the technical field of spacecraft dynamics tests, and in particular relates to a calibration system of a micro-vibration interference source test verification system and a calibration method using the calibration system of the micro-vibration interference source test verification system. Background technique [0002] Micro-vibration is caused by the normal operation of the on-board equipment (such as high-speed rotating parts such as momentum wheels, stepping parts such as solar wing drive mechanism, oscillating parts such as infrared camera pendulum mirror) or the small excitation of the space environment (such as The reciprocating motion of the overall and (or) local amplitude of the spacecraft is caused by thermally induced microvibrations generated by the spacecraft entering and leaving the earth's shadow. The presence of in-orbit micro-vibration environment will cause the relative movement of the pointing and target of the...
