Earth Observation System
From its more than 20 years of experience, SED continues to support the Earth Observation activities in numerous fields, including satellite data utilization estimation,feasibility study, research and development of onboard sensors, installation - operation - maintenance of Ground Data Processing Systems (Post Launch), related system evaluation, satellite data distribution, study of observation data utilization, and production of Multi-Media and Internet/Web contents.
Space Transportation Systems
Ever since its foundation, SED has contributed significantly to the aerospace development activities ranging from conceptual study through flight analysis to structural analysis. SED has participated in the development and operation of the Range Safety Systems that has been utilized for every Japanese launch since the successful launch of the N-I rocket in 1975.
International Space Station
SED has been a contributor to the International Space Station (ISS) program since its initial stages.
Once the ISS construction is completed, the lengthy ISS operational phase for the ISS will then commence.
From a technical prespective, through its contribution to the ISS preparations and operations, SED will continue to contribute to Japan's space development activities.
Tracking and Control Systems
With its vast experience in satellite tracking and control operations, SED is a leading contributor to Japan's satellite and control operation field. The tracking operation activities include, satellite data acquisition and tracking, while the control operation activities include, satellite operation planning and control.
SED monitors different types of satellites on a 24-hour 365-day basis. SED supports JAXA, at JAXA's main tracking center at Tsukuba, as well as, at three tracking and control stations in Katsuura, Masuda, and Okinawa. During the satellite launch preparation phases, SED provide support for Tracking and Control system design activities, which is one of SED's system engineering activities.
