The global space exploration market is currently undergoing unprecedented developments. Satellites, once only accessible to government agencies and billion-dollar corporations, have broadened their capabilities to allow Universities and start-ups to join in through the development of CubeSats. However, staying still in space is harder than initially thought, especially with the current expensive software solutions only being attainable for these bigger entities due to a lack of monetary resources.
Satellites undergo Micro Vibrations, typically having an amplitude in the order of microradians and a frequency range from 0.1 Hz to 100 Hz caused by onboard mechanisms such as gyroscopes. While this may seem insignificant, even the smallest disturbance can blur images and cause tracking inaccuracies. Just think about trying to take a super zoomed-in photo on your phone, but your tiny handshakes just make it a blurry mess. Therefore, small satellites must find innovative economical ways to minimize this effect, making it vital that satellites can simulate these vibrations before the launch.
