Abstract

Results of harmonic analysis of eight years earth tides observations with the borehole tiltmeter of the Poltava Gravimetric Observatory are presented. Hight-precision parameters of the main tidal waves and Love´s numbers h and k which practically coincide with similar data from  tiltmetric and gravimetric observations in 25 stations of Ukraine are received. The azimuthal inequality of a factor γ in the NS and EW directions isn't revealed. Resonant influence of the liquid core of Earth coincides with calculated theoretically.
