ESA said in Paris the radar satellite, launched in November 2025, completed in-orbit commissioning and now joins Sentinel-1C in the Copernicus programme.
Its synthetic aperture radar can image Earth's surface day and night in all weather, supporting disaster response, sea-ice observation, land-deformation tracking and deforestation monitoring.
Sentinel-1D is the fourth first-generation Sentinel-1 satellite; Sentinel-1B stopped collecting data after a 2022 technical failure, and Sentinel-1C launched in 2024 to restore the two-satellite constellation.
Since Sentinel-1D can now detect GPS jammers from orbit, how does this change the monitoring of electronic warfare?
With millions in sinking deltas now monitored from space, can this data force governments to finally address the crisis?
How will tracking ships that have gone dark alter maritime security and the enforcement of international sanctions?
