Abstract: Earthquake electromagnetic satellite mission planning is the center of satellite management in the orbit. This system's main tasks are 1) to optimize the satellite payload work plan based on the forecasting of regional space characteristics environment in orbit, 2 to get the characteristics space region observational data of the whole track, 3) to arrange observation data downlink. In this paper, the character of Earthquake electromagnetic satellite planning and scheduling system has been investigated. The fundamental principles for the mission planning have been found. The system structure based on the CCSDS standard is proposed. The function requirement and the planning process flow of the system have been analyzed. Then an Earthquake electromagnetic satellite mission planning prototype system is realized to test the feasibility of what we have presented in the paper. Finally, the paper gives the conclusion on the Earthquake electromagnetic satellite mission planning system and points out the system's latest developments trends and application requirement in the future.
