Scale factor is always one of the most important factors which affect the accuracy of relative gravity measurement. The scale factors from different calibration methods are used to calculate the same relative gravity measurement data and therefore the accuracy of the results are different. Based on the different scale factors of CG6 relative gravimeter(Calibration factor calculated by the gravity long baseline or the gravity datum points in the measurement area),the gravity measurement data of Tibet area in Crustal Movement Observation Network of China in 2019 and 2020 were calculated, and then the calculated results is compared and analyzed. The results show that the accuracy calculated by calibrating the scale factor between the gravity datum points in the measurement area is better than that calculated by calibrating the scale factor on the gravity long baseline.
