Ionosphere has an influence on different navigation, location and communication systems operation. Therefore radiowave propagation investigation problem are problem of today. Wave propagation had been investigated for the ionosphere model reconstructed by the radio-tomography in the case of the presence of equatorial anomaly. Results of modeling without taking into account the influence of a magnetic field of the Earth are considered. Ray structures are shown with using different radiation source location and frequency. Equatorial anomaly influence on radiowave propagation is analyzed. Dynamic model of ray structures was developed.
