ASNARO: Advanced Satellite with New system Architecture for Observation

ASNARO Project, started in JFY2008, is to establish next generation small satellite bus system based on open architecture technologies and manufacturing methodologies to drastically reduce the cost and the development period with adoption of up-to-date electronics technologies. The satellite bus system is composed of building block style of subsystem with the Space Wire network, and use high performance COTS, and improve verification test method. The first mission is earth observation with high performance optical sensor whose GSD is expected to be less than 0.5m from 510km SSO, and the total mass of the spacecraft is approximately 450kg. The spacecraft targets and takes user required images automatically with bus control system, and down link the data through high rate X band advanced data transmission system. The development of the spacecraft will be completed by the end of JFY2010, and expected to be launched in the year of 2011.
