Observing Systems Capability Analysis and Review Tool
Satellite Programme: Advanced Satellite with new system ARchitecture for Observation
Series of satellites for land observation.
Commercially-oriented Japanese programme: coordinated by USEF (Institute for Unmanned Space Experiment Free Flyer) and developed by NEC Corporation under sponsorship of METI (Ministry of Economy, Trade and Industry).
The platforms are actively stabilised over 3 axes.
The design life time is 5 years.
The satellites exploit sunsynchronous orbits around 11:00 (optical) or 06:00 (SAR).
Two satellites launched at short time interval provide complementary measurements, in optical and SAR bands.
See detailed descriptions at
Real-time transmission to ground stations in Hokkaido, Okinawa, Singapore and Svalbard (also for stored data). Further stations (also mobile) at appointed user sites.
All data concentrated to the Data centre by high speed ground links for processing and distribution.
