RTK surveying and mapping technology is simply a high-accuracy positioning technology, which mainly relies on Beidou and GPS technology to achieve land positioning work. Beidou is implemented all day long. The GPS global positioning system sends the data observed by the system to the main observation station, and it can also complete data transmission in different places. The observed data are accurately analyzed through the technology of mobile observation stations. Compared with traditional surveying and mapping technology, RTK surveying and mapping technology has great advantages. It is more flexible and convenient, has high efficiency, and is not easy to be interfered by the outside world. It can ensure high quality while ensuring efficiency.
