During line measurement ， sometimes we could not find the tie points of traverse and the visibility of ground surface would influence the implementation of conventional measurement with the development of GPS and the emergence of RTK technique, the accuracy of field survey has been up to cm. it has bee a sufficient tool in the fast data collect and positioning. It has the advantages: on time ability, high accuracy, fast speed etc, which the conventional survey doesn’t this paper the work model of RTK technique in survey, the structure of the data chain, the character of technique, the operation method of RTK, the error source of RTK, precision analysis etc are analysised and studied. Talk about the relative questions in road certain survey both with the coordinate calculation, coordinate transfer, elevation adjust etc, At last point out the correspond Mathematics model and the processing the application GPS RTK in control survey、 route survey、 centerline survey、layout and other aspects, we regard the it as a important technique revolution, it contains a huge technique potential in highway survey.
