The photoelectric tracker is interfered by carrier’s swaying which is the key factor of preventing the stabilization and the tracking precision from being improved. Firstly, based on control theory, this article compared direct-stabilization with indirect-stabilization. Secondly, the mathematic model of indirect-stabilization on two-axis optoelectronic tracking platform is established. Finally, a two-axis optoelectronic tracker used indirect-stabilization method to stabilize the tracking platform. Furthermore, the servo system of the two-axis optoelectronic tracker was designed and used effectively.
