Abstract

Positioning, Navigation and Timing (PNT) services have become the backbone to nearly all facets of modern life. Any disruption of space-based PNT services, whether intentional or accidental, could have dramatic consequences for national security, public safety and economic prosperity. In consequence, states owning, operating or merely using Global Navigation Satellite Systems (GNSS), and there regional counterparts, have grown extremely concerned with the reliance of their infrastructure, and its ability to provide stable and trustworthy PNT signals. This viewpoint provides a summary to global approaches of the state's ‘ensurance’ of PNT system resilience. Clear themes are highlighted and discussed, suggesting pathways forward to delivering a PNT infrastructure that can ensure the trust of governments and their users.

确保PNT在航行不确定时的弹性

定位、导航和授时（PNT）服务已经成为现代生活几乎所有方面的支柱。天基PNT服务的任何中断，无论是有意的还是意外的，都可能对国家安全、公共安全和经济繁荣造成严重后果。因此，拥有、运营或仅使用全球导航卫星系统（GNSS）的国家及其区域对应方，对其基础设施的可靠性及其提供稳定和可靠的PNT信号的能力变得极为关注。这一观点为国家“确保”PNT系统弹性的全球方法提供了总结。会议强调并讨论了明确的主题，提出了提供能够确保政府及其用户信任的PNT基础设施的前进道路。

期刊介绍： Space Policy is an international, interdisciplinary journal which draws on the fields of international relations, economics, history, aerospace studies, security studies, development studies, political science and ethics to provide discussion and analysis of space activities in their political, economic, industrial, legal, cultural and social contexts. Alongside full-length papers, which are subject to a double-blind peer review system, the journal publishes opinion pieces, case studies and short reports and, in so doing, it aims to provide a forum for the exchange of ideas and opinions and a means by which authors can alert policy makers and international organizations to their views. Space Policy is also a journal of record, reproducing, in whole or part, official documents such as treaties, space agency plans or government reports relevant to the space community. Views expressed in the journal are not necessarily those of the editors or members of the editorial board.
