High-precision coordinate transformation algorithm for equidistant transverse cylindrical projection

The aim of the present study is to design an algorithm for direct and inverse transformation of geodetic coordinates and flat rectangular coordinates of equiintermediate transverse cylindrical projection, based on the use of geocentric coordinate ellipses. Methods. General scientific methods of abstraction, analysis, synthesis, and mathematical modeling have been deployed to substantiate the coordinate transformation algorithm. Results.

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.
