Chen Jun-lin · Geomatics & Spatial Information Technology · 2011
GPS-RTK real-time dynamic measurement technique is the second after the GPS global positioning technology,mapping the field in another technological revolution,it has changed the traditional measurement mode.With the continual emergence of new mapping technologies and development of fast,flexible and efficient GPS-RTK for the mapping work has brought a new breakthrough in its increasingly broad application prospects.The working principle of GPS-RTK,accuracy analysis,the factors affecting RTK measurement and reliability issues were discussed in this article.Combined with a number of engineering practice,some to improve GPS-RTK technology in the routine control of measurement accuracy and reliability of measures and proposals,has got to be operational and practical significance.
