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 ê which practically coincide with similar data
from tiltmetric and gravimetric observations in 25 stations of Ukraine are received. The azimuthal inequality of a factor ó in the NS and EW
directions isn't revealed. Resonant influence of the liquid core of Earth coincides with calculated theoretically.
Key words: borehole tiltmeter, earth tides, tiltmetric observations, harmonic analysis, tidal parameters, Love's numbers,
resonance of the Earth's core.
