PNT智能与智能PNT

定位(positioning)、导航(navigation)、授时(timing),简称PNT,是人类在长期感知、认知宇宙与人类生存的关系后,产生的与经济、社会活动密切相关的时空位置概念。PNT也是地球上的物质、能量和信息经过亿万年进化出的感知、认知与时空位置相关的智能,称为PNT智能或时空智能。而智能是生命体为适应环境生存,通过一代代继承、演进而进化出来的趋利避害行为能力的总和,可称为自然智能。本文分析了依托于生命体物质基础的自然智能特性,在此基础上探讨了生命体PNT智能的特点;概述了人类研究生命体PNT智能的最新成果、趋势和启示。其中,交互智能和PNT智能等在生命体由低级向高级的进化过程中,特别是在智人进化并形成人类文明的过程中,起到了关键性的推动作用。随着自然智能、PNT智能、人工智能研究的深入推进和交叉融合,PNT技术发展也进入智能PNT阶段。本文着重阐述了智能PNT的概念、内涵和发展趋势,从PNT应用和时空信息基础设施建设两方面,探讨了其智能化热点方向的最新进展和影响。在此基础上,也提出了一些智能PNT发展的思考和展望。

PNT intelligence and intelligent PNT

Positioning, navigation and timing (PNT) are spatio-temporal location concepts closely related to economic and social activities generated by human beings after long-term perception and cognition of the universe and the relationship with human existence. PNT is also the intelligence that the matter, energy and information on the earth have evolved over hundreds of millions of years to perceive, recognize and position related to space-time, which is called PNT intelligence or space-time intelligence. Intelligence is the sum of the ability to seek benefits and avoid harm that has been inherited and evolved from generation to generation in order to adapt to the environment. It can be called natural intelligence. In this paper, the characteristics of natural intelligence based on the material basis of living body are analyzed, and the characteristics of PNT intelligence of living body are discussed. This paper summarizes the latest achievements, trends and enlightenment of human research on PNT intelligence in living organisms. Among them, interactive intelligence and PNT intelligence played a key role in the evolution of living organisms from lower level to higher level, especially in the evolution of Homo sapiens and the formation of human civilization. With the development and integration of natural intelligence, PNT intelligence and artificial intelligence, the development of PNT technology has entered the stage of intelligent PNT. This paper focuses on the concept, connotation and development trend of intelligent PNT, and discusses the latest progress and influence of intelligent hot topics from two aspects of PNT application and spatio-temporal information infrastructure construction. On this basis, some thoughts and prospects for the development of intelligent PNT are also put forward.
