Ionospheric delay correction method for LEO satellite augmented navigation systems
The invention discloses an ionospheric delay correction method for LEO satellite augmented navigation systems for GNSS. According to the method, GNSS satellite navigation signals received by LEO GNSS receiver loads are used for providing ionospheric information for navigation augmentation for earth surface users. In the method, as a set of mobile navigation augmentation reference stations, LEO satellites continuously observe the global ionosphere to generate ionospheric delay correction information, and the ionospheric delay correction information is sent to the earth surface users to obtain augmented navigation performance. By adoption of the method, ionospheric delay correction data covering the whole world instead of covering certain areas and particularly ionospheric delay correction data covering the vast marine areas are obtained; ionospheric gradient data are provided; and compared with traditional approaches, ionospheric delay correction accuracy is higher than that of traditional approaches; ionospheric activities and events are monitored in orbit to provide complete ionospheric delay correction information.
