SYSTEM FOR CORRECTING OUT OF GPS ZONE OF NUMERICAL MAP USING VRS

摘要

The present invention relates to a system for correcting out of GPS zone of a numerical map using VRS capable of determining error of the numerical map in out of GPS zone with a low communication efficiency with a GPS satellite or a regular observatory and precisely correcting the error. According to the present invention, an existing numerical map can be complemented with high reliability by determining network RTK-based coordinates using VRS and determining whether to correct the out of GPS zone of the existing numerical map to perform modification process. Further, a numerical map having high reliability without limitedness for the coordinates of a particular method can be completed since the uncertainty of the numerical map for a specific position can be tracked.
