Manifestation of Lunar and Solar Tides in the Spectra of GPS Coordinate Data

详细

The results of spectral analysis of coordinates obtained by continuous data acquisition using a stationary GPS receiver at the Mikhnevo Geophysical Observatory, Institute of Geosphere Dynamics, Russian Academy of Sciences, are presented. A detailed analysis of the digital data series recorded over a long period of time (observations have been carried out starting from June 2014) shows that the spectrum of coordinate data variations incorporates a considerable amount of quasi-harmonic components, including fluctuations with periods similar to those of waves of tides.
