Analysis and Prospect of Dynamic Measurement Technology for Cold Atom Gravimeter

To study the dynamic measurement of the cold atom gravimeter, the basic principle and experimental system of cold atom interferometry gravity measurement is introduced. The experimental process and results of the cold atom gravimeter applied to field dynamic measurement by domestic and foreign research teams are summarised. Several crucial technologies of dynamic gravity measurement are analyzed in detail, including large load and high precision inertial stabilization platform, high sampling rate atomic gravity measurement, error evaluation and correction, and combination with classical inertial sensors, and some application prospects are put forward. Compared with static gravimetry, dynamic measurement poses new challenges to the compactness, stability, dynamic measurement range, transportability, high sampling rate, and resistance to vibration and noise of cold atom gravimeters. It requires higher accuracy and sensitivity of gravimetry in a dynamic outdoor environment. Its vast development potential and challenges coexist.
