Dynamic gravity measurements can improve the efficiency of the gravity field survey, and thus play an important role in the field of basic geological surveys, resource exploration, and geophysical research. Based on cold atom gravimeter, inertial stabilization platform and the movable vehicle device, a system of dynamic measurement of the absolute gravity has been built, and the dynamic experiments have been carried out. Firstly, the noise power spectra of the vertical vibration have been measured, and their influence on the measurement of absolute gravity has been analyzed theoretically. Besides, the influence of moving velocity of the movable platform on the contrasts and offsets of the atomic interference fringes has been evaluated. The effect of vibration compensation in the dynamic measurement environment has been analyzed. When the maximum moving speed is 5.50 cm/s and the maximum vibration amplitude is 0.1 m/s2, the atomic interference fringes are still can be rebuilt base on the technology of vibration compensation. Based on the mentioned vibration compensation technology, the absolute gravity value has been estimated in the dynamic measurement environment base on the obtained atomic interference fringes of different T. After the correction of the systematic system and subtraction by the initial value of absolute gravity, the final measured result is (-1.22±2.42) mGal. Finally, this value has been verified by comparing it with the measured value in the static measurement environment where the accuracy is much higher. The experiment of dynamic measurement of the absolute gravity presented in this paper may provide the helpful reference data for the dynamic measurement of the absolute gravity with moving vehicles.
