The Copernicus L-band ESA SAR Sentinel-1–2 radar mission, named ROSE-L (Radar Observing System for Europe), provides enhanced continuity for a number of Copernicus services and downstream commercial and institutional users. It should be launched in 2028 and will work in synergy with other Copernicus elements to specially address emergency management service requirements. It should offer the same coverage and same frame as Sentinel-1 (swath widths around 250 km) to exploit synergy with a repeat coverage of less than one day in Arctic areas, three days in Europe and six days everywhere using two satellites (Pierdicca et al. 2019). Spatial resolution is expected to be better than 5 m x 10 m.

Data access: The main characteristics of the ROSE-L mission, dedicated to operational services, include reliability, data timeliness, a European free and open data policy, systematic acquisitions, a reduction in the number of payload modes and coordinated operations with Sentinel, and these distinguish ROSE-L from the other SAR mission initiatives.
