The invention relates to a thruster on-orbit autonomous diagnosis method based on a gyroscope and an accelerometer, thrusters comprise an attitude control thruster and an orbit control thruster, and the method comprises the following steps: S1, performing attitude control thruster autonomous diagnosis based on gyroscope measurement information; s2, on the basis of accelerometer measurement information, orbit control thruster autonomous diagnosis is carried out; and S3, performing thruster reconstruction based on the self-diagnosis result of the thruster. According to the method, program control diagnosis can be carried out on whether the thruster of the aircraft is effective or not, and autonomous reconstruction of the thruster is carried out according to the diagnosis result, so that the on-orbit safety of the aircraft is kept while tasks are completed.
