□ Outline of Technology
- A three dimensional rigid ball actuation system is a new concept of next generation actuator that can be replaced with the conventional general actuator used for attitude control and momentum storage, and is capable of accurately controlling the orientation in a three-axis direction by rotating a spherical fly wheel in a desired direction.

■ Problems of conventional art
• A conventional actuator operates in a manner of generating a single axis control torque, and requires at least three actuators to control an attitude of a satellite in a three-axis (X, Y and Z) direction.
• Since a plurality of actuators are used for the purpose of three-axis attitude control, there are problems with an increase in costs, volume and weight, and ensuring technical/economic competitiveness of a atellite shall be taken into account.
