Abstract
A methodology has been developed to form SBAS ionospheric grid points, based on the data from ionosphere radio occultation monitoring systems such as COSMIC. This methodology facilitates calculation of vertical delay of SRNS signals on frequency L1 for any geographical location. The corrections are used by a singlefrequency consumer for improving the accuracy of its position estimation in solving the navigation problem. Using the combination of ionosphere model and the data from radio occultation monitoring systems, it is possible to form real-time corrections in global scale, and to make their short-term forecasts. The proposed method testing results showed good conformance with the data from vertical probing stations, and the magnitudes of vertical delays of signal on frequency L1, represented by EGNOS system as differential corrections for consumers.
