The present application relates to the technical field of positioning, and discloses an ionospheric scintillation early warning method and device, a receiver terminal, a medium, and a product. The ionospheric scintillation early warning method comprises: acquiring a first ionospheric amplitude scintillation index of at least two satellites of a GNSS and a pierce point position corresponding to each satellite in the at least two satellites; acquiring parameter information and data quality information of a target reference station; according to the first ionospheric amplitude scintillation index, the pierce point position, and position information of the target reference station, determining a target ionospheric amplitude scintillation index corresponding to the target reference station; determining an amplitude scintillation index threshold for the ionospheric scintillation early warning of the reference station according to the target ionospheric amplitude scintillation index and the data quality information;
