Title:
BROADCAST-BASED GRIDDING DIFFERENTIAL DATA BROADCASTING METHOD, SERVER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/007022
Kind Code:
A1
Abstract:
Disclosed are a broadcast-based gridding differential data broadcasting method, a server, and a storage medium, comprising: partitioning a target region into a plurality of grid sections according to a preset radius; determining reference points among the grid sections; setting virtual stations for the grid sections according to the reference points; generating, according to differential data of the virtual stations, data packets to be transmitted; and broadcasting the data packets to be transmitted in a broadcasting way. According to the present invention, the baseline distance of a single section is shortened, and the positioning accuracy is improved, so that proper differential data can be selected in order to reach the optimal positioning enhancement effect.
