Study of the near-Earth environment with the global navigation satellite system

We discuss the technique of study of the Near-Earth environment with Global Navigation Satellite System data by means of the total electron content and navigation satellites phase slips metering. We analyze global electron content data as well as the near-Earth disturbances influence on positioning with the use of Global Navigation Satellite Systems and present the details of the Siberian GPS/GLONASS receivers network implementation. Results of detection of ionosphere response to solar terminator and different intensity of earthquakes are shown as well
