国产JSZ—4型接收机对子午仪卫星的时间同步试验

于一九八二年七月至十二月在临潼利用国产JSZ—4型多卜勒接收机,通过美国子午仪卫星进行定时试验。对比对的资料进行部分计算。结果表明单圈定时精度±30μs,比对精度±10μs,基本可以满足国内一些使用单位的需要。     

陕台TTR—6接收机存在的问题及其对国际比对的影响

陕西天台（CSAO）用于国际时间比对的GPS接收机TTR－6存在的各种问题，诸如天线有不正常的方向特性，跟踪卫星的时间长度不够780s，有约7天周期的系统波动等等。这些问题在一定程度上影响了CSAO的钟参加国际原子时（TAI）计算时所进行的时间比对精度，也影响了TAI－TA（CSAO）的稳定度和UTC－UTC（CSAO）的准确度。章通过数据分析阐明了问题所在，并说明其影响。     

国际原子时及NTSC守时工作进展

介绍了国际原子时(TAI)、协调世界时(UTC)以及我国标准时间UTC(NTSC)的产生和发展。简要介绍了国际标准时间的定义、国际时间比对技术的发展、TAI和UTC计算方法、工作规范的发展和未来可能的形态。介绍了我国原子时工作的历史和发展,以及时间基准保持性能、国际比对及溯源和时间信号服务方面的最新进展。
