Abstract
To provide GNSS/SBAS reliable performance under Space Weather impacts several solutions are considered. The system of technical-organizing measures that will enable to improve the GNSS performance quality with allowance for current helio-geophysical conditions is proposed. Exact fore- and nowcasting positioning quality under geomagnetic disturbances is out of modern state of technologies. Nevertheless, the forecasting may be proposed as a general measure to alert GNSSSBAS users for the probable abnormal state of the positioning in advance and in the nearly-real time. Real-time alert of users to a geomagnetic disturbance in the signal propagation medium is considered as enhancement of RAIM solutions. A complex system of differential correction, prediction, and monitoring of the GNSS positioning quality under unfavorable helio-geophysical conditions is proposed. The system is considered as a basis for a perspective service of global monitoring and forecasting of the integrated uniform GNSS current operation quality.
