Research Progress on High-precision Navigation Technology Based on Quantum Sensors

Quantum sensors have the potential to transcend the limitations of classical measurements. Substituting classical sensors with quantum sensors and developing high-precision quantum navigation technology emerges as a potential technological approach to boost navigation capabilities. Nevertheless, the engineering progress of quantum navigation technology has been sluggish, mainly constrained by several issues which include the complexity of quantum navigation systems, the degradation of measurement accuracy in dynamic environments, and the relatively large size and weight. In this paper, drawing on quantum navigation experiments conducted in recent years, the latest solutions to the aforementioned problems are systematically reviewed. Moreover, the most promising development directions are identified, aiming to provide valuable references for the engineering advancement of quantum navigation technology.
