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 as supplement 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 through technology development and R&D projects

CDR (Call Detail Record) data analysis system
• System has already been developed and a cloud system is being developed
• Input data are CDR data and some others, which depend on the output requirement
• The system structure is flexible for adding data analysis modules upon the output requirement
