【摘要】 RTK技术的出现,使得野外实时测量精度达到厘米级,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。本文比较分析了常规RTK系统和网络RTK的优缺点,并详细介绍了单基站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。更多还原

【Abstract】 The emergence of RTK technology,the RTK-GPS positioning can be achieved cm level precision in the field. 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.In this paper compare the characteristic of general RTK and network RTK,introduce characteristic of the single base difference system,at last analyze the accuracy and the effective distance of single based Differential GPS system.更多还原
