Analysis of flywheel disturbance and measuring technology

Flywheel has been identified as one of the main disturbance sources that affect the precision of attitude control system of spacecraft. In this paper, the main sources of vibration disturbances from flywheels were analyzed. The disturbance measuring technology used by some research centers were introduced and reviewed, which included NASA Goddard Space Flight Center, Tsukuba Space Center of the National Space Development Agency of Japan and MIT Space Systems Laboratory. This paper is helpful for establishing flywheel disturbance measuring system.
