In the laser inertial confinement fusion experiment, aiming at the urgent need for quick and accurate positioning of the diagnostic experiment equipments, the quick positioning and aiming method of using the laser tracking measurement system is proposed. The four-beam laser tracking measurement system is used as the aiming and positioning equipment, the mathematical model of the measurement system is developed, and the theoretical calculation of the aiming and positioning accuracy of the measurement system is carried out based on the least square method. When the measurement error of the laser trackers is 5 μm, the theoretical calculation angle error is 0.7492″, and the distance error is 11.2083 μm. When the measurement error is 10 μm, the angle error is 1.12″, and the distance error is 18.2167 μm. The theoretical calculation results indicate that the aiming method based on the laser tracking measurement system meets the quick and accurate positioning requirements of the experimental devices in the laser inertial confinement fusion. It provides theoretical guidance for using laser tracking measurement system as aiming and positioning equipment in China’s laser inertial confinement fusion device in the future.
