| Abstract: | The problems for attention in the use of HLS in a large scope were discussed.On the basis of the earth tide theory,the influences of the local gravity anomalies caused by the nearby masses or the gravity of the moon and the sun,on the surveying accuracy of hydrostatic levelling system and the related correcting methods were anlyzed,and the correcting formula was deduced. |

| Keywords: | hydrostatic levelling system(HLS) gravity gravity anomaly surveying accuracy correcting method |
