摘要
介绍四渡河特大桥GPS控制网,采用一种新颖的平差计算方式,解决了与周边控制网的接边精度问题,解决了大山区大高差对GPS施工控制网的精度影响。实际验证了国产单频静态GPS接受机,也能进行高精度的施工控制测量。
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.
