Research Progress on Dynamic Measurement of Cold Atom Gravimeter

The dynamic measurement technique based on cold atom gravimeter is distinguished from the application of relative gravimeter dynamic measurement of gravity value method, which has the outstanding advantages of high accuracy, no drift, long-term stable measurement, etc. However, the gravimeter from the static bench experiment to the dynamic measurement in the field is still affected by multiple factors such as the volume, the dead time, the noise, and so on. This paper summarizes the research progress of the dynamic measurement technology of cold atom gravimeter at home and abroad. First, it discusses the basic principle of cold atom gravimeter, analyzes the miniaturization and inertial stabilization platform, vibration isolation and damping, “dead time” compensation, combined measurement and other dynamic error suppression techniques. Second,it details some representative work carried out by the cold atom gravimeter in the integration of dynamic measurements in the land, sea, sky and space.Finally, it looks forward to the new methods and the military and other applications of cold atomic gravimeter measurement techniques.
