RUNNING STATE AND QUALITY EVALUATION OF REPEATED GRAVIMETRY

Xiang Aiming1,2),Sun Shaoan1,2)and Li Hui1,2)(1)Institute of Seismology,CEA,Wuhan 4300712)Crustal Movement Laboratory,Wuhan 430071)  
The quality and the accuracy of repeated gravimetry data since 1990 are analyzed.The results shows that the running state is stable and the quality of the data is good,both of the mean squares errors with unit weight and gravity value at each point of the data reach or closes to 10×10-8ms-2,thus the repeated gravimetry has already had the ability to detect the non-tidal gravity changes caused by tectonic activities.
