| Abstract: | In order to solve the problem of a hybrid inertial navigation system applied in a small missile-borne inertial navigation system, the characteristics of this technology are discussed and three key technologies for the small missile-borne hybrid inertial navigation system are proposed, i.e. the technology of miniaturization, anti-vibration and high-reliability locking, and self-calibration of anti-disturbance based on the reduced-dimension Kalman filter. The specific technical solutions and ways for the third technology are proposed. Firstly, based on the error model of the inertial navigation system, the self-calibration flow of the hybrid inertial navigation system is designed according to the observability of the attitude precision factor (ADOP). Secondly, the dimension reduction and anti-jamming observation design of the Kalman filter are carried out. Finally, the calibration test, mechanical environment test and navigation test are carried out. The experimental results verify the feasibility of the technical scheme and the correctness of the self-calibration algorithm, and provide engineering reference for its applications in small tactical missiles. |
