In Summary, we aim to ・・・
1. Provide information/data and platforms related
to Space as an open community, e.g.
Satellite monitoring and communication services
through nano-satellites
Positioning services
Data analysis services and GIS data development assupplement data for the data analysis

2. Build global networks and communities to link
Japan and Asian countries
3. Facilitate the creation of new business
opportunities
4. Strengthen technical competitiveness throughtechnology development and R&D projects 6

the output requirement• The system structure is flexible for adding data analysis
modules upon the output requirement
