摘要

高精度时频比对是现代科学技术的核心需求之一.然而，现有的技术受限于比对系统测量水平和链路系统误差处理算法，严重限制了时间比对性能的提升.针对这些问题，本研究搭建了基于中国空间站的高精度星地微波时频比对系统，并提出了一种基于双向测量的空间站-地面时频比对技术（三频模式），包括了对各项链路系统误差精细化建模新方法.通过对不同星地时频比对场景的仿真模拟发现，在配置高精度原子钟（10

）进行星地时频比对的场景下，经过本文算法优化后的比对长期性能仍可达与原本星地时钟相近的性能.利用中国空间站所搭载的氢钟与地面氢钟进行初步比对试验结果表明，在300 s可视弧段内的空间站-地面时间比对精度可达到10.77 ps，相应的ADEV（Allan DEViation）达到9.992 1×10

Abstract

High-precision time-frequency comparison is a crucial demand in modern science and technology. Yet

the performance of current technologies is significantly hindered by the measurement capabilities of comparison systems and the error processing algorithms of link systems. Addressing these challenges

this study establishes a high-precision satellite-ground microwave time-frequency comparison system based on the China Space Station (CSS)

introducing a novel satellite-ground time-frequency comparison technique that employs two-way measurements (tri-frequency mode) and includes advanced methods for detailed modeling of link system errors. Simulations across various satellite-ground time-frequency comparison scenarios reveal that

even with high-precision clocks (10

-15

to 10

-17

)

the long-term performance of the comparison

optimized through our algorithm

can achieve near-original satellite-ground clock performance. Preliminary comparison tests using the hydrogen maser clocks on the CSS and the ground demonstrate that

within a 300-second visibility arc

CSS-ground time-frequency comparison precision can reach 10.77 ps

with an ADEV (Allan Deviation) of 9.992 1×10

closely matching simulation results. This resea

rch provides new theoretical foundations and technical references for precision time-frequency synchronization technology.
