| Summary: | Satellite telecommunications, positioning and navigation systems require
knowledge of the electron distribution in height Ne(h) to high-altitude
orbits of satellites. One of the possibilities to construct such profiles is
associated with the use of the ionospheric total electron content TEC. This
paper is devoted to three advantages of the IRI-Plas model. They include
introduction of the topside basis scale height Hsc, expansion of the IRI
model to the plasmasphere, ingestion of experimental values of TEC. Testing
of this model according to different satellite experiments (CHAMP, DMSP)
shows the high efficiency of this model. The method of adaptation of the
IRI-Plas model to the plasma frequency at altitudes of CHAMP and DMSP
satellites allows us to produce behavior of Ne(h)-profiles during the
disturbances, as well as to refine the values of TEC, which determine the
accuracy of positioning. Results were obtained using data of the European
area. |
