The possibility of solar flare detection using data derived from the GPS/GLONASS navigation systems is demonstrated. Sudden increase of the total electron content (TEC) in the ionosphere is investigated on the basis of GPS data. The dependence of the TEC variations on solar ultraviolet and X-ray ionizing fluxes is analyzed. A technique of using the TEC variation rate to determine the effective intensity of solar ionizing radiation during a strong flare is proposed.
