A self-controlled, self-powered experiment support system called “OSVI: Observation System of
Convection-Diffusion phenomena with Vibration Isolation” was designed for a space experiment on diffusion
phenomena to extend our understanding of g-jitter. The system can simultaneously observe non-isolated and
isolated phenomena, enabling the g-jitter effect to be distinguished from pure diffusion phenomena. An
engineering model of the support system was developed and its functions successfully validated by parabolic
flights. To further increase the chances of the experiment being selected for space flight, the model has been
improved by using new passive dampers to reduce weight, increase controllability and provide power
distribution, in addition to some general improvements. The dampers have been validated by parabolic flight
experiments, which confirmed that much greater damping and a lower resonant frequency have been achieved.
Our experiment support system is now awaiting a flight opportunity.
