Abstract The drift model,regression factor of airpressure and disturbance eliminating of VAV and ETERNA tide analysis methods are compared and studied theoretically. Then further,the data observed with superconducting gravimeters at Wuhan station are analyzed by use of these two relevant softwares,we can get smaller stand deciation after interation from VAV than ETERNA method, but the differences between the analyzed value and the theoretical amplitude factor is at the same level.
Key words ：
VAV tide analysis method
ETERNA tide analysis method
