Abstract:
Time synchronization is an important factor for operational running of meteorological satellite ground stations. time standards consist of Universal Time (UT), Atomic Time (AT) and Universal Time Coordinated (UTC). Time services could be done by short-wave radio, GPS satellite and other special instruments. Time error could lead the system running in a disharmony way, and might make the task failure partially or completely. Firstly, time transmission way and time standards used in the operational system is introduced. Secondly, time service by GPS satellite, which can be adopted to achieve the time synchronization, is also introduced. Finally, the error of the above discussed time service is analyzed. The project has been applied to operational ground system of meteorological satellite successfully and will benefit to other applications, such as radar network systems, automatic meteorological network stations and so on.
