GPS-RTK误差来源及减弱误差的实用方法

GPS RTK Error Source and Practical Method to Reduce the Error

介绍GPS-RTK的工作原理,并从几方面对RTK误差产生的原因进行分析。通过不同观测方案及实测数据的对比分析,得出在既有技术条件下削弱GPS-RTK测量误差的方法,在对影响RTK可靠性及内、外符合精度因素进行分析后,给出提高RTK可靠性和测点精度的方法和措施,为测绘生产提供理论依据和技术支持。

This paper introduced the working principle of GPS-RTK,and analyzed the causes of error of RTK from several aspects,through the compare of the different observation scheme and the measured data,obtained the method to weaken the GPS-RTK measurement error under the condition of existing technology,after the analysis to the method of reliability in affecting the RTK and internal and external factors of precision,puts forward the methods and measures for increasing accuracy of RTK reliability and measuring point,provides the theoretical basis and technical support to the thought of surveying and mapping production.
