Abstract
The mainstream of the research and development of satellites in NASDA is for over 1 ton-class satellite. But, 50kg-class Micro satellites and under 10kg-class Nano satellites are researched, too. "μ-Lab Sat" -the first Micro satellite in NASDA- is planning to launch in 2002. The orbit of this satellite is LEO (low earth orbit) and the attitude of this satellite is the spin stabilization mainly, and the three-axis stabilization in the experiment. "μ-Lab Sat 2"-the next micro satellite in NASDA, is under conceptual study. It has 30kg-class mother ship satellite and 5〜10kg-class daughter-ship satellites. The orbit of this satellite is GTO (geostationary transfer orbit) and the attitude of mother ship satellite is the three-axis stabilization. Daughter-ship satellites will be formation flying in the experiment. The formation flying is the key technique for the interferometer.
