Abstract

Abstract: For the optical axis stability problem of airborne laser communication, a coarse and fine tracking system is proposed. The installation structure of the shock absorber is analyzed. Avibration reduction system is designed, and the servo system is simulated. On this basis, the vibration and movement characteristics of the aircraft are measured. The measured results meet the laboratory simulation input. The simulation tests and the field tests of tracking accuracy are carried out. The reults show that, under the condition of atmospheric channel, the tracking accuracy of coarse tracking system is better than 23.97 μrad, and the tracking accuracy of fine tracking system is better than 7.03 μrad. The results are greater than the laboratory simulation test results, which provide a reference for the system index allocation and the improvement of pod accuracy.
