RESULTS OF RESEARCH ON THE OUTER REGION OF THE IONOSPHERE, FROM OBSERVATIONS OF THE RADIO SIGNALS OF SPUTNIK 1. CALCULATION OF MAXIMUM DISTANCE OF RADIOWAVE PROPAGATION IN THE OPTICAL GEOMETRIC APPROXIMATION, FOR A SPHERICAL EARTH,
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 N(z) 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.
