Abstract:

In view of the vulnerabilities inherent in satellite navigation system timing， the U.S. military initially proposed the concept of timing warfare， underscoring the necessity for enhanced emphasis on timing information within the positioning， navigation， and timing （PNT） architecture. This conceptual framework subsequently catalyzed the formulation of a series of legislative measures pertaining to timing security. Given the current academic vacuum in timing warfare research， in contrast to Navigation Warfare， this paper systematically examines the conceptual underpinnings and policy evolution of timing warfare， delineates its potential operational manifestations， surveys relevant technological capacity development， and analyzes illustrative cases of timing-related conflicts. Ultimately， it elucidates the strategic implications of the timing warfare concept's emergence and evolution for China's national timekeeping infrastructure development.

摘要：

针对卫星导航系统授时的脆弱性，美军率先提出了授时战的概念，并强调美军需加强对定位、导航和授时（positioning，navigation and timing，PNT）体系中授时信息的重视程度，并在此后出台了一系列与授时相关的法案。基于当前授时战的研究尚属空白，与导航战对比，主要分析了与授时战相关的概念以及相关政策发展，阐述了授时战潜在的表现形式，介绍了相关授时技术能力建设和与授时战有关的案例，最后讨论了授时战概念的提出与发展对于我国时间体系建设的启示。
