| Abstract: | GPS - RTK has been used in many important engineering applications with its efficient and accurate measurement of advan- tages. However, the traditional instrument accuracy is comparable in the different measurement range. Firstly, this article will introduce the principle of work and the accuracy of RTK briefly, and then compares it with the traditional measuring instrument with engineering measuring example accuracy on elevation and coordinate measurement in different measurement range. Secondly, this article analyzes the scope of application of the two methods and the reasons affecting the accuracy. Finally, the author puts forward some useful suggestions and conclusions, in order to practice measurement and accuracy maximization benefit to practical engineering measurement and teaching. |
