| description | This paper presents an innovative space laser ranging technology that utilizes time-frequency co-transfer, effectively meeting the critical demand for precision in space laser ranging applications. The aim is to achieve high-precision ranging by calculating the transfer time using a bidirectional comparison scheme for clock synchronization and an active compensation technique for frequency transfer. Experimental results indicate that, over a 500 m optical path, an impressive ranging accuracy of 0.0005 m is achieved, reflecting significant improvements in precision, stability, and resistance to interference. By integrating time synchronization, frequency transfer, and free-space laser ranging into a cohesive system, this technology demonstrates substantial potential for a wide range of applications. |
