Abstract: In order to analysis the current drift characteristics and provide basis for the data processing, we calculated the dynamic and static drift rate of the dual survey observation data of Hebei area during 2019 and the test data. The results show that:（1）the CG-5 gravimeter static observation data shows good linear character;（2）the averages of static, dynamic or mixed zero drift rates are similar, which means the two gravimeters both show well stability;（3）in the measurement, the drift rate will be affected in many cases, such as when the time interval between the measurements is inconsistent.
