Description
The Active Weightlessness System is a specialized ground-based test equipment developed for conducting modal testing of spacecraft under simulated weightlessness conditions. Its primary purpose is to facilitate the testing of large transformable spacecraft systems, such as reflectors with diameters up to 50 meters, ensuring their proper deployment and structural integrity in a simulated space environment. The system, released in 2014, offers an active suspension mechanism that not only supports the large-sized transformable spacecraft systems but also simultaneously estimates dynamic parameters like velocity and acceleration with reference to an absolute time scale. This capability is crucial for understanding the dynamic behavior of spacecraft components during deployment. The product has a guaranteed service life of 3 years and an estimated production/delivery time of 12 months. It also offers the possibility to be adapted to specific customer requirements, providing flexibility for various testing scenarios.
