国家综合PNT体系弹性概念

The Concept of Resilience of National Comprehensive PNT System

  • 摘要: 对当前中美两国各自提出的弹性PNT (positioning, navigation, and timing)概念进行了深入分析, 并指出相互之间的差异和问题。特别针对未来国家综合PNT体系的主要需求特点, 从弹性概念的内涵入手, 提出PNT体系弹性能力的指标可分为外力干扰特性、内在技术特性和性能效果特性三类; 同时, 考虑到不同层次的PNT体系设计差异问题, 将PNT弹性化问题分为用户级弹性、系统级弹性和体系级弹性三个层次。笔者试图通过上述工作为中国在PNT体系领域的理论研究工作提供帮助。

     

    Abstract: We make an in-depth analysis of the concept of resilient PNT (positioning, navigation, and timing) system put forward by the United States and China, and point out their differences.Especially in view of the main requirements of the future national comprehensive PNT system, the concept of resilience is expounded that the resilient index of the PNT system can be divided into three categories: external force interference characteristic, internal technical characteristic and performance effect characteristic.At the same time, considering the differences of different levels of PNT system design, PNT flexibility is divided into three levels: user-level resilience, system-level resilience and system-level resilience.Based on the above work, it tries to help promote the theoretical research in the field of PNT system in China.
