MEASUREMENT OF ELECTRON CONCENTRATION IN THE UPPER IONOSPHERE BY THE COSMOS ARTIFICIAL EARTH SATELLITES.
Abstract
One of the formulas serving to determine the electron concentration of the ionosphere is presented. The refractive index of the ionosphere depends on three coordinates and time. The formula is derived on the basis of measurements of the phase difference of coherent radio waves radiated by transmitters installed on satellites and rockets. The results of such measurements obtained by utilizing the radiation of the Mayak radio transmitter on board artificial earth satellite Cosmos-11 are discussed. A nonmonotonic curve of electron concentration along the orbit above the main ionization peak is detected. The hypothesis of a 'compression' of the upper ionosphere during the transition from maximum to minimum solar activity is confirmed. A maximum is detected at 150-180 km in the spectrum of the dimensions of the inhomogeneities of the outer ionosphere. The irregular slopes of electron concentration in large inhomogeneities attain tens of percent in relation to the regular value of N. (Author)
