摘要
RTK测量具有实时性好、精度高、速度快等优点,是常规测量所无法比拟的,RTK已经作为快速采集数据与定位的有效工具,但在山区线路测量中仍受到许多限制,尤其是无线电传输距离的限制。详细介绍了基站GPS差分系统的特点,并在实际工程应用中对其精度和有效距离进行了探讨。
RTK survey have advantages of good real-time quality, high accuracy, quick speed. The normal survey can＇t be compared with RTK survey, for the reasons, it has become an effective tool in the rapid data collecting and positioning, but it has many disadvantages, especially the distance of the radio wave which GPS RTK used. This paper introduces the characteristic of difference GPS system; at last analyze the accuracy and the effective distance of single based Differential GPS system.
