In order to study geodynamic effects and solve high-precision geodesy problems, geodetic measurements, including gravimetric measurements, have increased accuracy requirements. Currently, gravimetric measurements are performed by modern electronic gravimeters. It is known that the sources of errors affecting gravimetric measurements are instrumental errors (reference error, level errors, elastic hysteresis, power instability, calibration function errors) and errors caused by the influence of the external environment (temperature, atmospheric pressure, magnetic field and shaking). In addition to the above, it is also known that gravimetric measurements are influenced by another factor – the gravitational field of the Moon and the Sun. Taking this influence into account is important when it comes to tasks in which measurements are subject to increased accuracy requirements, for example, geodynamic effects or high-precision leveling processing. The initial data for this study are the coordinates (in the geodetic coordinate system, BLH) of the points of the Earth’s surface and the ephemeris of the Moon and the Sun. The mathematical apparatus for calculating corrections is implemented in the interactive environment for numerical calculations MATLAB. The result is the calculated components of the lunar-solar tides, expressing a quantitative change in gravity
