A service is described that makes possible the effective construction of a three-dimensional ionospheric model based on the data of ground receivers of signals from global navigation satellite positioning systems (GNSS). The obtained image has a high resolution, mainly because data from the IPG GNSS network of the Federal Service for Hydrometeorology and Environmental Monitoring (Rosgidromet) are used. A specially developed format and its implementation in the form of SQL structures are used to collect, transmit, and store data. The method of high-altitude radio tomography is used to construct the three-dimensional model. The operation of all system components (from registration point organization to the procedure for constructing the electron density three-dimensional distribution and publication of the total electron content map on the Internet) has been described in detail. The three-dimensional image of the ionosphere, obtained automatically, is compared with the ionosonde measurements, calculated using the two-dimensional low-altitude tomography method and averaged by the ionospheric model. © 2014 Pleiades Publishing, Ltd.

Further development of the method of transionospheric radiosounding of the ionosphere in the range of its plasma frequencies is presented. The trajectories of radiowaves with a reflection from the Earth are newly included in the consideration. A modeling of the transionospheric radiosounding was performed in conditions of an irregular ionosphere including moderate-dimensional irregularities with drawing possible trajectories, as well as the obtainment and analysis of the corresponding transionograms. © 2014 Pleiades Publishing, Ltd.
