授时信号 meaning in Chinese
time signal
Examples
- Time service is a important content in seismic observation . measure precision of time - synchronization effects the quality of recording
本文给出了一种应用在宽频带地震记录仪中基于gps授时信号的时间同步技术。 - Gps is a planet wireless conductance system which is global and all - weather , gps can offer high precision time orientation information to infinite user , clock precision reachs 10 ? 6 magnitude 。 not only changes traditional time method of quartz crystal clock , but also replaces wireless shortwave and even more lowfrequency signal and tv signal whose overlay range is limited and low precision , offers advantage to geology field task , achieve automatization and high precision of seismic flow observation
利用gps授时信号全方位、全天候、连续性、实时性和高精度的特点,以gps信号为基准来校准本地时钟(晶体振荡时钟或原子钟) ,将gps接收机输出信号的长期稳定度和恒温晶振的短期稳定度相结合,应用大规模可编程逻辑器件,设计和实现了由pc104控制的实时在线授时系统。
