METHOD FOR CONSTRUCTING DATA BASE FOR GPS LOCATION USING ENVIRONMENTAL INFORMATION

摘要

The present invention relates to a method for constructing a GPS location information error correction DB (DataBase) using environmental information, and to immediately correct an error of GPS location information generated according to various weather information according to each weather information. The present invention relates to a method of constructing an error DB for correction of GPS location information.;To this end, the present invention selects a plurality of reference stations having different peripheral information, receives GPS signals transmitted from a plurality of GPS satellites in close proximity to the reference stations, and acquires GPS location information in various weather environments. Comparing the acquired measurement position information and fixed position information by calculating and storing the error according to various weather information of a plurality of reference stations, it is possible to build an error DB according to various environmental information (ambient information and weather information) It is done.;GPS, GPS receiver, location information, surrounding information, weather information, correction, error
