Title:
INTEGRITY DETECTION METHOD AND SYSTEM FOR INTEGRATED NAVIGATION DATA
Document Type and Number:
WIPO Patent Application WO/2024/046341
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of navigation positioning, and provide an integrity detection method for integrated navigation data. The integrity detection method for integrated navigation data comprises: obtaining original navigation data; performing original data integrity detection on the original navigation data to generate first severity data; processing the original navigation data according to a preset integrated navigation algorithm to obtain a positioning result; performing process integrity detection on an operation state of the preset integrated navigation algorithm to generate second severity data; performing result integrity detection according to the positioning result to generate third severity data; obtaining integrity detection information according to the first severity data, the second severity data and the third severity data; and generating a confidence coefficient of the positioning result according to the integrity detection information. According to the integrity detection method for the integrated navigation data, the technical effect of improving the reliability and stability of integrated navigation can be achieved.
