Paper Abstract

Critical frequencies specified by the IRI model are determined for a given hour at two closely adjacent space points. A correction parameter is differences between pseudo-distances of signals from a pair of navigation satellites, recorded by a single-frequency receiver. We compare the differences calculated from measurements of the total electron content at frequency correction points and from the model with fitting of critical frequencies at these points. It is shown that in most cases the similarity between model and experimental values of the pseudo-distances difference exists when critical frequency variations do not exceed 30%.
