Application and accuracy analysis of GNSS-RTK technology in data acquisition

Abstract

With the development of electronic equipment such as total stations, GNSS, digital cameras, and computers, surveying and mapping technology has moved from analog measurement to the era of digital mapping. The field of surveying and mapping has ushered in earth-shaking changes. Using GNSS_RTK field-wide digital mapping is one of the most basic methods. It is more efficient than other field data collection and is widely used in topographic surveying. The increasing development of GNSS makes the production process more convenient and faster, and the advent of RTK technology also breaks the limitations of traditional conventional measurement methods, completes the accurate positioning in the coverage area of the reference station network, and also promotes the more in-depth application of RTK technology in the traditional field. Compared with traditional mapping technology, GNSS-RTK technology has the advantages of more efficient, more accurate, easy to save and convenient for later modification, etc., and well maintains the current trend of the result map. This paper discusses the GNSS-RTK technology, the method of GNSS-RTK technology in field acquisition, and the application and accuracy analysis of GNSS-RTK technology in field collection.
