Summary
The flywheel is essential in controlling the satellite’s flying attitude under the steady state. Its control system guarantees the reliability and lifecycle of satellites in orbit. With the adoption of an integrated design of flywheel body and control circuits, the product, minor in size and weight and supporting both speed and torque controlling modes, has already been applied to many of the in-orbit satellites of Jilin-1 series.
