ABSTRACT
To control the satellite in ground, the control scheme of satellite ground application system is designed in this paper. It is responsible for task scheduling, system monitor and system coordinate. As the nerve center of the ground system, the control scheme uses a mixture of C/S and B/S architecture based on its characteristics. There are many tasks need be scheduled by the ground application system, such as the time, the scheduled and the data reprocessing. Due to the complexity of data processing process, the operation control subsystem uses a hierarchical scheduling module to reduce scheduling complexity. In addition, the system uses the automatic operation mode, including the development of pre-business operation plan, the distributed task scheduling and the centralized status monitor.
