Abstract Zero drift stability is an important performance parameter of the CG-5 gravimeter, determining the accuracy of the instrument to a great extent. The zero drift stability can be divided into static zero drift stability and dynamic zero drift stability. Based on the zero drift stability analysis of four CG-5 gravimeters purchased at different times, we evaluate the static zero drift stability of CG-5 gravimeter using the correlation coefficient of the fitted linear, and evaluate the dynamic zero drift stability of CG-5 gravimeter using average dynamic zero drift rate. The experimental results show that the method can effectively evaluate the zero drift stability of the CG-5 gravity meter.
