Satellite radiosounding of the ionosphere from heights near to a maximum of F2 layer

The generalized results and experience in the field of carrying out the experiments on the ionosphere radio sounding at the “MIR” manned space station (heights 340 – 390 km) are presented and analyzed. New multi frequency paths for radio wave propagation between the satellite and Earth, new data about the local specific macro irregularity in ionosphere and an adaptation of the IRI model by experimental data and some other factors were shown.
