Methods and software for calculating total electronic content based on GNSS data
Keywords:Ionosphere, Radio tomography, Total electronic content, Global navigation system
Methods for determining the total electron content in the ionosphere by global navigation system signals are investigated. Methods for correction phase ambiguity due to «cycle slip» and determining differential code delays are proposed and implemented. Software for finding the full electronic content and constructing maps of vertical full electronic content over the territory of the Republic of Belarus was developed.
