摘　　要：全球导航卫星系统(GNSS)是提供定位导航与授时(PNT)服务的重要手段。可替代GNSS技术作为GNSS不可用时持续提供PNT的一种新方法,成为各国研究的重要方向。文中聚焦2021年度国外PNT领域的发展,以PNT体系的发展为统领,从战略规划、技术及装备应用层面概述国外基于导航战制定的相关规划、取得的技术进展及开展的相关系统装备级验证试验。GNSS is an important means to provide positioning, navigation and timing(PNT) services. As a new method of continuously providing PNT when GNSS is not available, alternative GNSS technology has become an important direction of research in foreign countries. This paper focuses on the development of foreign PNT area in 2021. Guided by the development of PNT system, this paper summarizes the plans, technical progress and system and equipment level verification tests relative to NAVWAR based on strategic planning, technology and equipment application.
