DGPS Implementation Using Multiple Reference Stations

摘要

The present invention relates to a method for implementing DGPS (Differential Global Positioning System), and to providing a more accurate and stable position measurement by using a plurality of reference stations by using position error correction information generated from multiple reference stations. It is about. The present invention includes a plurality of reference stations that receive a signal from a GPS satellite to produce a position error correction value, and obtains a user's position using the position error correction values generated by the plurality of reference stations. It provides a method for implementing DGPS using stations, which entails improving the accuracy, stability, economics and efficiency of the system compared to a single reference station DGPS system.
