Abstract: With the development of receiving equipment and SBAS constellation the
dual frerquency L1 and L5 transmissions compatible with GPS signals are now
available from a number of geostationary satellites. These signals can be used
for ionospheric TEC measuremets by the analogy with GPS/GLONASS signals. In
this work we present the results of the estimations of geostationary TEC
variations at the mid-latittude receiving station in Moscow, comparison with
ionosondes data as well as wavelet spectra of TEC variations with typical
periodical components. We also demonstrate the possibilities of SBAS TEC
studies in connection with Solar flares.
Key words: ionosphere, total electron contene, Solar flares, remote
sensing, satellite navigational systems, GPS, GLONASS, SBAS.
