Аnnotation: First of all, in the paper some of the distinctive features of the first domestic program for Earth tides prediction ATLANTIDA3.1._2014 in comparison with similar programs of foreign authors are discussed, as well as some examples of practical application of the program by some researchers are given. Further, the main functionality of the program is listed. Among them, the possibilities for calculating the amplitude delta factors of tidal waves for the Earth without the ocean, as well as amplitude delta factors and phase shifts for the Earth with the ocean, time series of the tide, amplitudes and phases of the oceanic gravimetric effect are highlighted. A brief description of the theoretical developments included in the program is given. In this regard, the main differences of the latest version of the program are highlighted. The theoretical values of the amplitude delta factors for an inelastic self-gravitating rotating Earth, calculated taking into account the action of relative and Coriolis accelerations, as well as dissipation, are considered in detail. In total, 12 variants of models are considered, differing from each other by the turning on or turning 0ff of separate factors affecting the result. Evaluation of proximity of the results of the program and observations made on European superconducting gravimeters of the Global Geodynamic Project (GGP) is given. It is shown that by this criterion our program surpasses the most well-known analogs in the world practice. In the conclusion of the paper, a list of tasks is given, the solution of which will further expand the functionality of the program and lead to refinement of the results already obtained so far.
