Basic Concepts of Radiation Biology,ect the performance of satellite navigation. Therefore, civil aviation standards require that the impact of ionospheric anomalies (especially ionospheric storms) should be considered in integrity monitoring. To meet the safety requirement of satellite navigation service in civil aviation, it is urge
