|Summary:||The scale factor of the superconducting gravimeter(SG) at Jiufeng gravity datum station was calibrated by co-located absolute gravimetry with an FG5 absolute gravimeter(AG).The data processing results show that the mean scale factor is -76.960±0.085×10-8ms-2/V, the accuracy level is about 0.1%, the scale factor obtained by absolute gravimetry for 2 days(about 5000 drops)is nearly stable and the accuracy is better than 0.2%.|
