Results Development of QM level model of 5Nm-control moment gyro (CMG) for high mobility earth observation satellite.

Expected Contribution
■ economic effects
- For development of High Mobility satellite is a trend worldwide, if you develop successful, it is expected to export a large effect on the world market is in technology-rich countries, behind the United States and France. In other words, the effect is expected to export 60 billion won and (20 billion 2020-2022 Years) import substitution of 20 billion won (~ 2025).

■ technical effect
- By developing a momentum wheel of precision driving, technical ripple effect is greater in cooperation in the development of applicable reaction wheel to satellite for practical use.

- It can be applied to a drive device (stabilization of the attitude and direction change), compact, high torque attitude control (Vehicle) moving various body are required, in particular support the main field of application the CMG, (Floating it is utilized can be very useful to the mobile that moves by being). (Sample usage: satellite, oil unmanned aircraft, missile, robot, ship stabilization device, such as a deep-sea submersible)
