Problems solved by technology

If the method of using traditional satellites to test similar components separately, it will be unbearable in terms of time and economy for the thermal vacuum test of micro-nano satellite components
However, if different temperature control requirements and different types of micro-nano-satellite components are tested in the same group, it will also face the problem of how to solve the problem of differential control and personalized thermal characteristics
