Error modeling and compensation for indirect stabilization electro-optical targeting system

  • In order to improve the precision of indirect stabilization electro-optical targeting system, the line-of-sight error model of the system was established. The rotation-modulation approach was studied for alleviating the drift error of the gyro. The speed measurement method by combining tachogenerator and photoelectric encoder was proposed for decreasing quantization noise of the photoelectric encoder. The relationship between the installation error of gyro & camera and line-of-sight stabilization error was analyzed, and the installation error was effectively estimated by using electro-optical tracking method. The theoretical analysis is consistent with the real experimental results. The simulation results show when the system error was completely compensated, the accuracy of indirect stabilization system based on low performance micro electronic mechanical system (MEMS) gyros was equal to the direct stabilization system based on medium performance fiber gyros.
