%X As the GPS method is different from deformation measuring methods with extensometer and horizontal pendulum tiltmeter at the aspect of having source, point observation, data composition, data deleting, data preprocessing, comparing datum,the sole basic data and so on. In order to understand the particularity of GPS survey, taking earth tide as the surveying object, GPS is compared with the convention deformation measuring methods here. The results at YANQ, DSQI, BJSH and other stations show that the earth tide surveyed by GPS is similar to the theoretical value and the data observeed by conventional deformation measuring instruments such as extensometer, but the amplitude of GPS result is bigger than others, as the max amplitude difference in one day of vertical-component can achieve 100 mm.
