Title:
IONOSPHERIC SCINTILLATION EARLY WARNING METHOD AND DEVICE, RECEIVER TERMINAL, MEDIUM, AND PRODUCT
Document Type and Number:
WIPO Patent Application WO/2024/066476
Kind Code:
A1
Abstract:
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; and according to a real-time ionospheric amplitude scintillation index and the amplitude scintillation index threshold, determining whether the ionospheric scintillation early warning is carried out on the target reference station. According to embodiments of the present application, the ionospheric interference to the reference station can be early warned.
