The applicability of the clock server refers to the achievability of its functions, that is, the time source and time service methods that are often mentioned in the time-frequency environment we mentioned earlier. For a normal clock server, it mainly meets the requirements of the time source, that is, the requirements of the time service mode in the time service environment. In addition to the requirements for timing accuracy or punctual accuracy, it is the main function of the clock server in actual work. , Other parameters can be ignored or stated separately in normal use. For the clock source part of the clock server, in most cases the most accurate and most commonly used one is to select Beidou/GPS/GLONASS and other satellites to receive time synchronization. The advantage is that after connecting to the satellite time once, the clock server can keep communicating with the satellite. The time is synchronized from time to time, every second is not bad, it is convenient for users to use for a long time, and there is no accumulated error. The only disadvantage is that it is recommended to erect the satellite antenna on the roof of a building or an open location, which requires trouble in the early stage of the project.
