GNSS METHOD AND SYSTEM FOR GNSS IONOSPHERIC OBSERVATION VALIDATION

摘要

The present invention relates to a system for verifying GNSS ionospheric spatial tilt measurements in areas where the GNSS ground station distribution is less dense. More specifically, the spatial and spatial analysis of ionospheric anomalies using ionospheric anomalies through geographic adjacent GNSS ground station search, satellite-ground station combination classification through pattern recognition, final gradient candidate extraction, and threat visualization are applied to the actual phenomena. It is related to a GNSS ionospheric spatial slope measurement verification system that can be used to verify whether or not due to a receiver or post-process error. The present invention provides a system and method for verifying whether extreme GNSS ionospheric slope measurements are due to actual phenomena or satellite / post-processing errors in situations where the GNSS ground station distribution is dense.
