Sentinel-1D is compatible with the Galileo navigation system and other Global Navigation Satellite Systems (GNSS).
Arquimea developed essential thermal control system components for the Sentinel-1D satellite and manufactured heat pipes that transfer heat between subsystems.
Sentinel-1D is designed to provide high-resolution radar images regardless of weather conditions or sunlight.
Sener designed and manufactured the deployment and locking mechanism for the main instrument of Sentinel-1D, the Synthetic Aperture Radar (SAR).
GMV developed the mission control center for Sentinel-1D, located at ESA's Operations Center (ESOC) in Darmstadt, Germany.
The Sentinel-1D satellite is equipped with an advanced radar instrument that captures images of the Earth's surface under any weather conditions, including through clouds.
The radar instrument on Sentinel-1D was built by Airbus in Friedrichshafen.
The calibration of Sentinel-1D's radar instrument is supported by the DLR SAR Calibration Center in Oberpfaffenhofen.
With Sentinel-1D now operational, Europe maintains a robust monitoring capacity essential for environmental protection and safety.
Data was transmitted from Sentinel-1D to the ground station located in Matera, Italy, part of the Copernicus ground segment.
Sentinel-1D was launched on November 4 aboard an Ariane 6 launcher from the European spaceport in French Guiana.
After entering orbit, Sentinel-1D, equipped with a 12-meter synthetic aperture radar (SAR) instrument, captured images over Antarctica and South America two days after its launch.
Data from Sentinel-1D was downlinked to the ground station in Matera, Italy, within 50 hours of launch.
The time from launch to data delivery for Sentinel-1D is believed to be the shortest for a radar-based Earth observation satellite.
Sentinel-1D reached its orbit after being launched successfully by the European Ariane 6 rocket from French Guiana.
Thales Alenia Space manufactured the Sentinel-1D satellite.
Liftoff of the Sentinel-1D satellite is expected to occur at 22:02 CET.
Sentinel-1D's radar vision will provide valuable data about the changing world.
Thales Alenia Space received 400,000,000 EUR in 2015 to build Sentinel-1C and Sentinel-1D for the European Commission’s Copernicus system.
The Sentinel-1D satellite is part of Copernicus, the Earth Observation component of the European Union’s Space Programme.
