摘要：Concerning the traditional methods, more technical details and more strict conditions are required for global positioning system (GPS) receiver’s calibration especially for mid and long baseline which influenced by the environment around easily, and more investigations have to be done. In this paper, a new method on how to calibrate GPS receivers is suggested, which is based on the convenient condition that Kunming has one international GPS service station and its own continuously operating reference stations, and the method is confirmed by a test using six different types of GPS receivers. Compared with the traditional methods, the new method is more efficient by decreasing routine calibration works up to 50%.
