This paper shows the preliminary design of satellite operation management system and initial operation case studies that achieve the reduction of human work time and human error in satellite operation and also quickly reflect the observation request of a data user. An unlimited number of satellites, ground stations, and users (including non-space operators) can be used within the capacity of the database. It is a platform for ground station sharing, satellite operation management support, satellite data archives and distribution. This system will be upgraded into an on-demand spectrum measurement service for non-space operators. Initial operation will start with 4 satellites and 3 ground stations managed by Tohoku University, and the system will be expanded to 10 satellites and 6 ground stations by the end of 2022.

The core Web services are SOM (Satellite Operation Management) and SDM (Satellite Data Management). Depending on operator or data user requests, the Web API automatically generate the tasks for satellites and ground stations. The system provide communication opportunities between ground stations and satellites, imaging opportunities using target point attitude control by satellites, and archiving of communication data and imaging data via the Internet. Full automation of satellites and ground stations is the goal, as immediacy is required from request to data distribution.

The system can greatly reduce the development efforts of especially new satellite operators and organizations. Planning work of satellite operations requires a great deal of time, and a solution to reduce human work time and human error must be required. Since the date and time of the communication task and the imaging task are calculated automatically, the command templates prepared for each task are combined after the task titles and time stamps are automatically modified. Operation planners only have to devote their efforts to final confirmation of each satellite-specific settings (power management, memory management, etc.), and have time to concentrate their efforts, such as developing final confirmation software specific to each satellite.
