Afterwards, the operation schedules for various events based on the results of these various event performances are established, and operations for events such as orbit adjustment plans, satellite tracking plans, and orbit decision plans are based on the experience of other operators and the experience of mission analysts. A schedule was set up and a schedule of tasks was created by manually entering these schedules on a monthly or weekly basis.

However, in the above-described conventional technique, it is difficult for the task analyst to effectively set an operation schedule when the task analyst individually executes the related programs and judges the results based on the results. Since the data must be input manually, the possibility of input error was high, and the schedule was determined through analysis based on various data. Therefore, the amount of work was huge and the work was very cumbersome.

In order to solve the problems described above, the present invention provides a simple input for analyzing various events required to automatically establish a mission analysis and planning schedule for stationary satellites operating in space in a satellite control system. It automatically executes the task schedule by automatically generating the task schedule for the predictable event and the user-specified event from the analysis result data, and the operation schedule related to the task and the remote command file name required for the task. The purpose is to provide a method for automatically generating a task schedule for generating a program.
