Abstract

In this paper,the mechanism of periodic errors of Lacoste and Romberg (LCR)G gravity meters is analysed.The principles and methods of calibration of pe-riodic errors are also discussed.By using the three terms of calibration observations of LCR-G920 and LCR-G922,the further study on periodic errors of LCR-G gravity meters is taken,and some conclusions are reached.
- periodic errors,
- error of thread pitch,
- measuring screw,
- gearbox,
- baseline calibration
