| 摘 要： | 激光时间传递技术是通过激光脉冲在空间的传播来实现地面与卫星时钟或地球上远距离两地时钟的同步，它具有很高的准确度和稳定度。一些国家已经成功进行了激光时间传递的试验，结果证明利用激光进行时钟之间的同步是有效可行的。介绍国内外已有的激光时间传递试验的情况和结果，重点介绍美国地面与机载原子钟之间的激光时间比对，以及法国的LASSO(LAser Synchronization from Stationary Orbit)和T2L2(Time Transfer by Laser Link)计划。

| Abstract: | Time transfer by laser pulses is based on the propagation of light pulses between satellite and ground clocks or between remote clocks on earth. It will realize the synchronization of these clocks with high accuracy and stability. Several experiments of the time transfer by laser pulses had been successfully carried out in some countries. These experiments validate the feasibility of the synchronization of clocks by laser pulses. The paper describes the results of these experiments. The time comparison by laser pulses between atomic clocks on aircraft and ground ones in the United States, and the LASSO and T2L2 projects in France are introduced in detail. |
