【Abstract】 The technology of GPS has been introduced in ground survey, and has been rapidly developed in the area of road investigating as well. When it comes to control survey of special engineering, there is great difference in the technology of survey and data processing between GPS and normal measurement. The aim of this article is to illustrate the setting principle, precision, and the work method of the control net for GPS used in the control survey of the second bridge of Zhengzhou huanghe river.更多还原
