摘要: 阐述了借助地面测控站对星载铷钟进行监测,以实现铷钟在轨运行频率特性的四种测量方法:单向时差比对法、双向时差比对法、利用GPS系统时间比对法和激光时差比对法,并对这四种方法的测量原理进行了分析和比较。对育种卫星搭载国产铷钟的试验方案和测量结果进行了介绍。

关键词: 铷钟, 时间比对, 频率稳定度

Abstract: Four methods which are based on acquiring frequency character of rubidium clock in orbit SatelliteGround measurement are proposed, including one way time difference antitheses, two way time difference antitheses, time difference antitheses via GPS, time difference antitheses by using laser. The theory of all the four methods is analyzed. The test design and results of rubidium clock which was a payload of breeding satellite are introduced.

Key words: Rubidium atomic clock, Time comparison, Frequency stability
