A methodology has been developed to construct SBAS ionospheric grid based on the data from ionosphere radio occultation monitoring systems such as COSMIC. This methodology facilitates calculation of vertical delay of GNSS signals on frequency L1 for any geographical location. The corrections are used by a single-frequency receiver for improving the accuracy of position estimation in solving the navigation...
The paper addresses the problem of required positioning accuracy to be provided for a marine consumer. To improve the reliability of navigation measurements, an option of system implementation comprising both stationary onshore facilities and mobile offshore ones is proposed. In order to ensure appropriate range and accuracy of navigation using surface radio navigation aids (RNA), it is proposed to...
