CONTENTS E.D. Tereshchenko, A.N. Milichenko, M.V. Shvets, S.M. Cherniakov, I.V. Korableva TOTAL ELECTRON CONTENT ESTIMSTION USING SATELLITES SIGNALS OF THE GLOBAL NAVIGATION SYSTEM GLONASS The smart estimation method of total electron content for signals of the global navigation satellite system GLONASS is presented. Comparison of calculated values of total electron content with obtained values of total electron content from data of other satellites and the global model UAM and the global ionosphere map GIM was done. Results have shown that the proposed method gave good agreement with results of the independent methods of total electron content calculations and can be an effective method of total electron content estimation from signals of the GLONASS satellites. Keywords: Global navigation satellite systems, total electron content, differential code biases. Authors Evgeny D. Tereschenko - Dr. Sc.
