Open publisher page 0 citations

Abstract

The emergence of RTK technology, the RTK-GPS positioning can be achieved cm level precision in the field. RTK survey have advantages of good real-time quality ,high accuracy ,quick speed .The normal survey can′t be compared with RTK survey ,for the reasons ,it has become an effective tool in the rapid data collecting and positioning .In this paper it was recounted the development of the RTK-GPS including measurement models, data chain structures and the technology characteristics, RTK work process, RTK production precision effect. Its application in the concrete highway survey work such as control , road and layout surveying was discussed.
