A Preliminary Exploration of the Differences and Conjunction of Traditional PNT and Brain-inspired PNT
🤖 AI Summary
Conventional PNT (Positioning, Navigation, and Timing) systems suffer from insufficient resilience, suboptimal energy efficiency, and a lack of cognitive capabilities. Method: This study proposes a “cognition-driven” general-purpose PNT paradigm to transcend the limitations of traditional “tool-oriented” approaches. We establish a multi-level comparative analytical framework integrating conventional PNT, biological-brain-inspired PNT, and neuromorphic PNT, and design a four-layer integrated architecture—Observation–Capability–Decision–Hardware—that unifies numerical precision with brain-like intelligence. The architecture synergistically incorporates neuroscience-inspired neuromorphic computing models and high-accuracy machine-based PNT technologies. Contributions: (1) First systematic definition of the technical connotation and developmental roadmap for neuromorphic PNT; (2) Establishment of an interdisciplinary PNT integration theoretical framework; (3) A concrete implementation roadmap for next-generation PNT systems featuring high accuracy, strong resilience, low power consumption, and spatial cognition—providing critical enablers for brain-like navigation in autonomous systems.

📝 Abstract
Developing universal Positioning, Navigation, and Timing (PNT) is our enduring goal. Today's complex environments demand PNT that is more resilient, energy-efficient and cognitively capable. This paper asks how we can endow unmanned systems with brain-inspired spatial cognition navigation while exploiting the high precision of machine PNT to advance universal PNT. We provide a new perspective and roadmap for shifting PNT from "tool-oriented" to "cognition-driven". Contributions: (1) multi-level dissection of differences among traditional PNT, biological brain PNT and brain-inspired PNT; (2) a four-layer (observation-capability-decision-hardware) fusion framework that unites numerical precision and brain-inspired intelligence; (3) forward-looking recommendations for future development of brain-inspired PNT.
