# geodetic coordinates

## Using dual-frequency GNSS observations to determine ionosphere parameters

The correlation between the measurement data of geodetic coordinates and data that describe the local state of the earth’s surface and near-earth space was researched. To identify the possible connection between the oscillating components of geodetic coordinates integrals calculated autocorrelation and cross correlation functions of integrals for a given period of time. Graphics autocorrelation function and investigated integrals are presented.
