Description

technical field

[0001] The invention belongs to the application fields of space weather monitoring and satellite navigation, and in particular relates to an ionospheric scintillation monitoring system for large-amplitude ionospheric scintillation. Background technique

[0002] Global Navigation Satellite System (GNSS), as an important infrastructure for countries in the information age, can provide more accurate positioning, navigation, and timing services on a global scale, and can also be used for ionospheric monitoring in space weather monitoring. scintillation monitoring applications, and using GNSS signals as beacons for ionospheric scintillation monitoring is an inexpensive means of monitoring.

[0003] Ionospheric scintillation will weaken the GNSS signal power, and the ionospheric amplitude scintillation index and ionospheric phase scintillation index can be estimated after the GNSS signal that passes through the ionosphere and reaches the earth's surface is received...
