| Abstract: | The emergence of RTK technology,the RTK-GPS positioning can be achieved cm level precision in the field.RTK sur- vey 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 effec- tive distance of single based Differential GPS system. |
