Abstract:

A possible method is examined for conducting satellite radio observations. The method is based on determining the moments of radio rising and radio setting, from which the electron concentration Nz of the ionosphere above the maximum level may be derived. Preliminary results from the analysis of the experimental data are set forth. The analysis of the results leads to certain important and interesting concepts concerning the outer ionosphere. Quantitative characteristics were derived for the decrease of the electron concentration and neutral particle density in this region also certain notions of the boundary where the atmosphere makes contact with the interplanetary gas.
