The research of the high precision electro-optical tracking system based on the vehicle platform is introduced, the system structure is designed. The platform is a T-shaped structure, and the high frequency vibration is separated by the whole vibration reduction. The control system is designed, the rough stabilization is realized by the gyro-stabilization device, the fine stabilization is realized by the high frequency fast mirror, and the stabilized precision is improved by the two-level stabilization platform combing the fine and rough stabilization. The simulation experiment is made and the system test is also made by the swing device which can simulate the vehicular environment. The experimental result shows that the system can achieve the high precision.
