中法之间通过laser链路进行时间传递
Time transfer by laser link between China and France
摘要:
从毫弧秒天文测量向微弧秒天文测量迈进,需要提高天文台的守时能力和不同台站间的比对能力。亚奥理事会和法国国家空间研究中心正在开发的T2 L2(通过激光链路进行时间传输)实验将于2008年在Jason-2上发射,该实验允许地球上的远程时钟同步。它基于光脉冲在空间中的传播,这比无线电波传播更好地控制。本文介绍了中法钟的共视和非共视T2 L2比对的特点。
英文摘要:
To advance from milli-arcsecond to micro-arcsecond astrometry, time keeping capability and its comparison among different stations need to be improved and enhanced. The T2L2 (Time transfer by laser link) experiment under development at OCA and CNES to be launched in 2008 on Jason-2, allows the synchronization of remote clocks on Earth. It is based on the propagation of light pulses in space which is better controlled than the radio waves propagation. In this paper, characteristics are presented for both common view and non-common view T2L2 comparisons of clocks between China and France.
