With the development of science and technology, GNSS technology has not only been widely used in traditional surveying and mapping, but also applied in engineering construction and engineering machinery. The 3D control technology is realized by satellite positioning, and the traditional construction method is changed to realize the optimization of engineering quality and construction efficiency. The application of GNSS technology in large-size construction machinery is the developing direction of the current and future construction industry. This sections shows products available for this area of operations.
