Correction method of the ionosphere model using data from wide area navigation satellite systems

A method of correcting an ionosphere model is developed on the basis of data received from wide area navigation satellite systems. This method allows one to calculate the distribution of electron concentration on a scale that is close to real-time, and it can be used in conditions of a disturbed ionosphere, where it is difficult or impossible to determine the critical frequency of the F2 layer. The ionospheric parameters received from vertical incidence sounder data and retrieved from the corrected model agree well, which allows this approach to be used for ionospheric support of different radio systems.
