1300 monthly series of continuous tiltmeter and gravimetric observations have been processed on 25 earth tide stations of Ukraine. High-precision regional parameters and of the main tidal waves, Love’s numbers and , differences of amplitude factors of diurnal tidal waves O 1 and K 1 have been received, which characterize the real physical properties and condition of the Earth’s core and promote a choice or construction of its most reliable model.

As a result of studying the peculiarities of the seismic waves velocities in the Kirovograd ore district Earth’s crust and its structures some regularities of the velocity characteristics of the structures under studying were revealed. It is shown that these structures were confidently marked out in the field of the seismic wave velocities. It opens some new possibilities for tectonic zoning of the Kirovograd ore district and the Ukrainian shield territory.

A method for determination of the difference in parameters of the Earth's tidal waves 0 1 and K 1 , which is generated by the Earth's liquid core and reveals itself in the dynamics of its surface, has been improved. The testing on the base of the experimental findings gathered on six tiltmeter stations indicates the improved accuracy in determination of the diurnal tidal waves parameters that can be used for modeling of the internal fine structures of the Earth.
