[Abstract]:With the development of science and technology, more and more new handsets are emerging and the precision is improving. Because of its small volume, convenient carrying, all-weather, omni-directional, real-time three-dimensional navigation and positioning ability, it has the advantages of high sensitivity, high precision, automation, cheap, easy to use, etc. The application and development of CORS technology is becoming more and more mature, which makes the accuracy and distance of conventional RTK work greatly improved. As a result of network technology, computer network management, With the development of radio communication technology and other factors, the measurement technology of handheld RTK receiver is more feasible. This paper summarizes the factors of GNSS,CORS, affecting the accuracy of GPS measurement and handheld machine, especially introduces the hand-held RTK measurement technology, the comparison and analysis of hand-held RTK accuracy, the comparison and analysis of hand-held RTK relative to conventional RTK accuracy, and the application of hand-held RTK in digital mapping. Compared with other measurement techniques, handheld RTK receiver measurement technology has more advantages. In the aspect of digital mapping, it can meet most of the mapping requirements. Therefore, the application of hand-held RTK receiver measurement technology in digital mapping has been a development trend, and its benefits are obvious to the surveying and mapping industry.
