The positioning principle of global positioning system and its application prospects

Abstract

Abstract Due to the continuous advancement of science and technology, more and more construction fields have realized the transformation from science and technology to productivity. Including GPS positioning technology. GPS (Global Positioning System) is a system that uses positioning satellites to achieve precise global positioning and can also navigate. The United States developed and used a satellite navigation and positioning system in 1994. The application of this technology has basically covered all areas of the national economy. GPS is widely used in ground surveying, engineering surveying, aerial photogrammetry, topographic surveying, etc. in the field of surveying. The application prospect of GPS system is introduced.
