摘要

GPS RTK(Real Time Kinematic)技术是指载波相位实时动态差分GPS定位技术，它

具有实时、定位精度高、操作简便等特点，被广泛地应用于地形图测绘、碎部测量等测量领域，是GPS发展的新形式，是GPS应用的重大里程碑。它的出现为各种控制测量、地形测图和工程放样等带来了曙光，极大地提高了测量工作的外业作业效率。为了扩大GPS RTK技术在测量工作中的应用范围，满足高精度的测量要求以及建立大面积的测量控制网的需要，拟通过具体的设计试验探寻出实用的测量方法来代替传统的常规测量方法，使测量工作更简便快捷。但是就目前来说，由于受卫星信号、接收机状态、测站周围环境及仪器操作的影响，RTK定位有时会出现失真，其成果不可能百分之百的可靠，为了将RTK更好地服务于测绘工程，有必要对RTK的测量精度进行研究和分析。

Abstract

The technology of GPS RTK, namely, the technology of the carrier phase real-time

dynamic differential positioning, has the characteristics of the real time, the higher positioning accuracy and the simplicity. The technology which is a new method of the development of GPS and a significant milestone of the application of GPS is widely used in topographic mapping, scattered measurements and other measurement fields. The coming of GPS RTK brings new dawn to all sorts of controlling measurements and the mapping of the geography and improves the efficiency of the field operations of the measurement enormously .I intend to seek out a practical measurement in place of the conventional one in order to expend the field of application of GPS RTK ,satisfy the demand of the precision and the requirement of establishing a widespread range of controlling of the measurement and make the measurement much easier and quicker . But now, due to the efffects of the satellite signal, receiver state, surrounding environment and instrument operation, RTK may be fuzzy sometimes, so the results cannot be reliable absolutely. In order to make RTK serve for engineering of surveying and mapping better, it is necessary to research and analysis the accuracy of RTK measurement.

The research content of this paper:

⑴Introduce the basic principle of GPS RTK.

⑵Compare and analysis the result of point coordinate by the observation of RTK and

result by the observation of static GPS, and use this detect the quality of RTK.

⑶Compare and analysis the results of point coordinate by the observation ofRTK and traverse points by the observation of total station, and use this detect the quality of RTK.
