| Abstract: | It introduces GPS control net for super bridge in Sidu River and a sort of novelty calculational method about adjustment, solves the problem about precision of circumjacent control net and the influence between GPS control neshwork and the high difference in mountainous area. It is proved that we can use monophonic static GPS set made in China for high precisional control survey. |
