Abstract: 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.

Key words: natural intelligence, artificial intelligence, embodied cognition/intelligence, PNT intelligence, intelligent PNT, spatio-temporal information infrastructure, cognitive navigation, semantic navigation, bionic navigation, brain-line navigation
