Abstract

Reception and processing of GNSS signals allows determining the full electronic content and monitoring of ionosphere parameters. Analysis of the receivers used by Russian experts to assess the Total Electron Content (TEC) shows that the measurement rate of GNSS signal parameters and the need for primary signal processing in the equipment do not allow recording fast-flowing (less than 0.2 s) processes in the ionosphere. To evaluate various ionospheric disturbances, it is proposed to record GNSS signals at a high frequency up to the initial processing stage with subsequent software processing of the recorded data. Options are proposed for constructing such a hardware-software complex for evaluating fast processes in the ionosphere. The proposed approach allows one to overcome discrepancies in the interpretation of measurements and calibration corrections for GNSS receivers.
