The zero-drift coefficient of gravimeter is of significance in the effective zero-drift correction of observation data and achieving reliable gravity data. The authors apply fuzzy weighted linear regression algorithm on the calculation of zero-drift coefficient. The results of trial, comparison and analysis based on the analog data and real data of gravimeter show that the algorithm is automatic calculation, can suppresse the noise effectively and get reliable calculating result, which can realize the effective calculation of the zero-drift coefficient and has future application potential.
