    Abstract
  • The relevant policies and overall goals in the field of USA positioning, navigation and timing (PNT) are combed through. The construction progress, service capabilities and fusion applications of important PNT information sources, such as GPS modernization, GPS and LEO communication satellite fusion, e-Loran system construction and autonomous navigation projects, are analyzed and summarized in detail. It indicates that the United States has clarified the development context of PNT system, and the related construction has entered the substantive stage. At the same time, this paper puts forward specific suggestions for the future development, integration and construction of PNT information sources in China.
