A structural model of the upcoming Copernicus Radar Observing System for Europe at L-band satellite, or ROSE-L for short, has recently been put through a series of demanding tests \u2013 including intense vibration \u2013 to demonstrate that the satellite will be able to withstand the stresses of launch and operations in orbit.<\/p>\n
Once in orbit, ROSE-L\u2019s data will support a wide range of applications, from soil moisture and crop monitoring to forest mapping, maritime surveillance, and the detection of natural and human-induced hazards.<\/p>\n
The five-week testing campaign took place at Thales Alenia Space\u2019s facilities near Rome in Italy, and although satellite engineers \u2018only\u2019 used a structural model, it carried the full weight of ROSE-L\u2019s ambitions.<\/p>\n
Every beam, panel, and bracket \u2013 its central cylinder spine, the upper and lower cones, and the launcher interface ring \u2013 was built to mirror the true satellite with uncanny fidelity. Many of these components will be refurbished and subsequently be used in the real satellite.<\/p>\n
Mass dummies were also bolted into place to mimic the heft of yet-to-be-installed systems: the wide-winged solar array, the radar antenna, and countless other components that will one day look down on Earth from orbit.<\/p>\n
ROSE-L then endured gut-punching sine vibration along all three principal axes, shaking with the same violence it will face atop a roaring rocket.<\/p>\n
It also braved the deafening acoustic onslaught meant to recreate the launch environment, sound so intense it becomes a physical force. Day after day, between October and the end of November, the satellite structure stood firm.<\/p>\n
\t\t\t\t\t\t\tROSE-L team<\/a><\/p>\n ESA\u2019s Project Manager for ROSE-L, Gianluigi Di Cosimo, said, \u201cThis was a very important series of tests, and we have seen that the satellite structure passed with flying colours. Our thanks go to the entire team, whose expertise and dedication were essential to achieving this milestone.<\/p>\n \u201cThe campaign actually began earlier in the year at SAB Aerospace in Brno in Czechia, where the structure passed its static load tests in July. It then moved to Rome for these dynamic mechanical tests, which have closed out the qualification programme.<\/p>\n \u201cWith this phase complete, attention now shifts to the upcoming integration of the actual satellite. This will take place in the newly-inaugurated Space Smart Factory in Rome \u2013 a 5000-square-metre facility featuring modular ISO 8 cleanrooms, advanced manufacturing tools, and a modern digital infrastructure aimed at streamlining satellite integration and testing.\u201d<\/p>\n
