Aim. In order to improve the definition of GNSS-stations coordinate changes, it is important to find out how the processes that occur in the near-Earth space influence the significance of these changes. To describe such processes we can use the seismic activity index, the infrasound rate, and the number of daily flashes in the Sun. In this regard the purpose of this work is to study the influence of the above processes on small changes in the coordinates of GNSS-stations. Method.
The paper presents some results of long-term studies of the association of seismicity of the Earth with solar activity using the database Word Data Centers for the solar activity and seismicity of the Earth.
The article shows the frequency of earthquakes on the rate of change solar activity. The method of superposed epochs was u sed.
In the paper the dynamic of solar activity and connected to it the geomagnetic field variations and its ecological disturbance on Ukrainis territory is analyzed. It is shown that solar activity concerning to the cycles with 100–200 years periods is in the state of transition to decreasing. Interconnection of the quasibiennial variations of solar and geomagnetic activities is studied. It is shown that ecological disturbance of geomagnetic field on Ukrainis the Ukrainis territory do not exceed of the quota.
The correlation between the values of geodetic coordinates obtained using GPS-observations and data that describe the local state of the earth's surface and near-Earth space was researched. We calculate autocorrelation and cross-correlation integrals of integrals of functions for a given period of time to identify the possible connection between the oscillating components of the geodetic coordinates and parameters that describe geo-seismic and solar activity
