The satellite will be placed in a sun-synchronous orbit at an altitude of around 700 km and will provide day and night data regardless of weather conditions. Thanks to its longer wavelength, it will be able to penetrate vegetation, snow, and ice, enabling detailed monitoring of forest conditions, soil moisture, glaciers, and sea ice. The mission will thus contribute significantly to monitoring the impacts of climate change and provide high-quality data for EU environmental policy.

The ROSE-L satellite will be the largest ever built with the participation of Czech industry – it measures over 5 meters and weighs about 2,000 kg. Its 11 × 3.6 m radar antenna will be the largest planar radar antenna used in a space mission. The company 5M s.r.o. from Kunovice is also actively involved in the project. After supplying 42 sandwich panels for the structural model and successfully completing static tests, it is continuing with the production of secondary structure panels for the pre-flight model of the satellite. It is collaborating on the project with the Brno-based company SAB Aerospace.

For 5M, participation in the ROSE-L mission represents a significant milestone. The company has long specialized in composite and sandwich structures for aviation and aerospace, and its involvement confirms that Czech technologies can meet the most demanding requirements of ESA space projects. The satellite is scheduled to launch in 2028 and its operational life is expected to exceed seven years.
