Abstract: FIELD: gravimetry.  
     SUBSTANCE: invention relates to the field of gravimetry and can be used to compensate for the nonlinear component of the zero-point drift velocity of a static thermostatic gravimeter. Essence: reference gravimetric measurements with simultaneous measurement of the temperature of the gravimeter body at different ambient temperatures are performed. High-frequency filtering of measurement results from microseismic noise, seismic events, lunar-solar tidal phenomena and the barometric effect is carried out. The linear and nonlinear components of the zero-point drift velocity of a static gravimeter are determined. An effective temperature model is created in the form of a set of first-order aperiodic links, the parameters of which are determined by the maximum correlation between the nonlinear component of the zero-point drift velocity of the gravimeter and the effective temperature. The dependence diagram of the nonlinear component of the zero-point drift velocity of the gravimeter on the effective temperature is created. The angle of inclination of the approximating straight line is determined, the tangent of which is the coefficient of conversion of the effective temperature into a correction that takes into account the nonlinear component of the zero-point drift velocity of the gravimeter. The current gravimetric measurements are carried out with simultaneous measurement of the temperature of the gravimeter body and determination of the linear and nonlinear components of the drift velocity of the zero point of the gravimeter. The effective temperature is determined by modeling. The correction compensating the nonlinear component of the zero-point drift of the gravimeter is calculated by multiplying the obtained effective temperature by the coefficient of conversion of the effective temperature into the correction. The corresponding value of the above correction is introduced into the nonlinear component of the drift velocity of the zero point of the gravimeter at the current gravimetric measurements.  
     EFFECT: increasing the accuracy of gravimetric measurements by reducing the temperature errors of gravimetric measurements with a static thermostatic gravimeter, increasing the duration of flights and reducing the number of reference points.
