PSEUDOLITE-BASED PRECISE POSITIONING SYSTEM USING SYNCHRONIZED TWO-WAY PSEUDOLITES

摘要

A pseudolite-based precise positioning system using synchronized two-way pseudolites is provided to enable each sub pseudolite to correct a clock of each sub pseudolite independently by generating visual correction information of a pseudolite at a reference station for pseudolite visual synchronization. A main two-way pseudolite module(701) has a reference clock of a synchronous pseudolite-based precise positioning system(700). At least one sub two-way pseudolite module(702a,702b,702c) is visually synchronized to the reference clock of the main two-way pseudolite module. A moving object(703) determines own position with a single positioning algorithm on the basis of a signal received from the main two-way pseudolite module and the sub two-way pseudolite module, without correction information through data link from a base station.
