Major results of researches conducted by Russian geodesists in 2019-2022 on the topics of the International Association of Geodesy (IAG) of the International Union of Geodesy and Geophysics (IUGG) are presented in this issue. This report is prepared by the Section of Geodesy of the National Geophysical Committee of Russia. In the report prepared for the XXVII General Assembly of IUGG (Germany, Berlin, 11-20 July 2023), the results of principal researches in geodesy, geodynamics, gravimetry, in the studies of geodetic reference frame creation and development, Earth's shape and gravity field, Earth's rotation, geodetic theory, its application and some other directions are briefly described. For some objective reasons not all results obtained by Russian scientists on the field of geodesy are included in the report.

“…At present, the uncertainty in measurements of free fall acceleration (FFA) by absolute ballistic gravimeters (ABG) attains microgal values (1 Gal D 1 cm/s 2 ) (e.g., (Vitushkin et al 2020)). The general operation principles of laser-interference ABG and the principles of absolute measurements of FFA with their help are presented, for example, in (Vitushkin 2014;Absolutnye gravimetry 2017;Niebauer et al 1995).…”

At present, the uncertainty in measurements of free fall acceleration (FFA) by the designed absolute ballistic gravimeter (ABG), developed in VNIIM, attains microgal values (1 Gal = 1 cm/s2). At such a high level of accuracy, the effects of the interaction of a test body (TB) falling in the vacuum chamber of the ABG in the geomagnetic field could comprise sources of systematic errors. Furthermore, individual units and systems of the ABG itself also can be sources of the magnetic field (MF). We report about more rigorous calculations of the possible effects than those performed in the past. A consecutive self-consistent method of calculation of the desired correction to the FFA has been developed. It results in the differential equation, including not only the field itself, but also its vertical first and second derivatives and variation of the velocity along the trajectory. The desired correction is obtained by its numerical solution on the basis of the parameters of the field generated by the magnet of the stepper motor. The derived correction proved to be at the level of a tenth part of microgal.

Global navigation satellite systems, which provide high accuracy of navigation, in certain conditions (in tunnels, in closed rooms, in conditions of interference, etc.) have restrictions on their use. In this regard, in order to ensure “seamless” navigation in any conditions of the situation, it becomes necessary to develop new methods and means to increase the stability of navigation definitions. The article is devoted to the consideration of the problems of creating an integrated navigation system using measurements of the parameters of the Earth’s gravitational and magnetic fields. Requirements for meters of parameters of geophysical fields and navigation charts are considered, a number of new navigation meters, new methods and means of preparing navigation charts are proposed. The ways of development of relativistic geodesy and the possibility of using the achievements of gravitational-wave astronomy in gravimetry are considered.
