    摘要:

    高精度时间频率信号稳定性和可靠性是现代导航的重要基础,直接影响系统时间基准和导航定位结果。为了保证高精度时间频率信号的稳定性和可靠性,研究时频信号完好性监测方法。并在此监测方法上,充分利用中国科学院国家授时中心生成并保持的UTC(NTSC)建立高精度时频信号监测系统。该系统可实时监测时频信号性能,检测异常,并及时响应以保证时频信号的完好性和系统时间基准的稳定性。完好性监测方法已被充分验证并应用到时频和导航系统

    Abstract:

    The stability and reliability of highprecision timefrequency signal is an important basis for modern navigation. It directly affects the accuracy of system time and navigation results. To solve the problem, the integrity monitoring method for physical time frequency signal has been researched on. In this paper, based on the proposed method, a highprecision timefrequency signal integrity monitoring system has been constructed using the UTC (NTSC) in National Time Service Center of Chinese Academy of Sciences. The system can realtime monitor the performance and the integrity of signal, immediately response to the trouble, resolve the problem and provide the highprecision physical signal more stability and reliability. The integrity monitoring method is verified and applied in many navigation systems and time frequency measurement systems.
