AI Technical Summary

Technical Problem

Existing technologies that utilize low-Earth orbit satellites to provide GNSS satellite augmentation services have issues affecting user positioning speed and accuracy, particularly in terms of resources and timeliness.

Method used

By acquiring GNSS satellite ephemeris data received from low-Earth orbit satellites and approximate location information of terminal equipment, and combining spatial geometric relationships, GNSS satellites visible to both low-Earth orbit satellites and terminal equipment are selected as target satellites. Navigation enhancement information is then broadcast via low-Earth orbit satellites to optimize satellite selection, thereby improving positioning accuracy and shortening information transmission time.

Benefits of technology

It improved the positioning accuracy of GNSS satellites and shortened the initial positioning time, optimized the resource utilization of low-orbit satellites, and enhanced the positioning performance of terminal equipment.
