Data Dissemination and Broadcast Disks at the fundamental and harmonic frequencies through 1000 Hz. NASA/GSFC personnel designed and implemented a low cost active counterbalance to mount on each expander to reduce vibrations. NASA/GSFC’s vibration control algorithm was then used to further null vibrations to below 0.1 Newtons..Character
