RTK POSITIONING SYSTEM AND POSITIONING METHOD THEREFOR

摘要

A system and a method for RTK(Real Time Kinematic) position measurement are provided to increase applicable area by using plural pseudolites. A rover receiver(5) measures a code and a carrier wave phase of a signal received from each of pseudolites(2). A fixed base station(3) is located at a preset position and measures the code and the carrier wave phase of the signal received from each pseudolite(2). A mobile station(4) measures the code and the carrier wave phase of the signal received from each pseudolite(2) and moves. A user processing unit(6) measures a position of the rover receiver(5) based on the code and the carrier wave phase of the signal received from the fixed base station(3) and the mobile station(4) and the code and the carrier wave phase received from the rover receiver(5). A data link(7) transmits data from the mobile station(4) and the rover receiver(5) to the user processing unit(6).
