Sentinel-1D

Leonardo supplied attitude sensors (Autonomous Star Tracker) and radar power units for Sentinel-1C and -1D.

Sentinel-1D incorporates a patented mechanism that separates the radar antenna from the satellite body during deorbiting, helping to reduce orbital debris.

Sentinel-1D will deliver day and night, all-weather radar imagery of Earth.

The acquired radar imagery from Sentinel-1D will aid in response to global disasters.

The Sentinel-1D satellite is equipped with a large deployable SAR (Synthetic Aperture Radar) antenna capable of providing continuous images of the Earth's surface in any weather conditions, both day and night.

Sentinel-1D will deliver all-weather, day and night radar imagery of Earth.

KSAT Kongsberg's Troll Satellite Station in Antarctica has received the first signals from the Sentinel-1D satellite.

Sentinel-1D completes the first generation of the Sentinel-1 radar constellation, enhancing the continuity and reliability of data for global environmental monitoring, emergency management, and security.

Leonardo contributed to the construction of the satellite Sentinel-1D with attitude control sensors made in Campi Bisenzio.

Data from the Sentinel-1D satellite will be collected by various European centers, including the Matera Space Center managed by Leonardo through e-GEOS.

Sentinel-1D, a new satellite, was launched into orbit by Thales Alenia Space at sites in Rome, Milan, and L'Aquila.

Sentinel-1D will provide all-weather, day and night radar imagery of Earth's surface.

Approximately 34 minutes after liftoff, Sentinel-1D was deployed from the rocket’s upper stage into a Sun-synchronous orbit at an altitude of 693 kilometres.

Both Sentinel-1D and Sentinel-1C carry a C-band synthetic aperture radar instrument and an Automatic Identification System instrument.

The Sentinel-1D satellite will provide accurate and reliable radar data to benefit citizens' scientific knowledge of the environment.

The operational capabilities of Sentinel-1D ensure continuity for Copernicus services amidst growing demand for geospatial data for civil, environmental, industrial, and security applications.

The patented mechanism of Sentinel-1D allows for the separation of the radar antenna from the satellite platform during atmospheric reentry to reduce space debris.

Ariane 6 successfully placed Sentinel-1D into Sun-synchronous orbit at an altitude of 693 km (approximately 430 miles).

The radar satellite Sentinel-1D travels at 25,000 kilometers per hour, 30 times the speed of a commercial airplane.

Both Sentinel-1D and Sentinel-1C are equipped with C-band synthetic aperture radar (SAR) for capturing high-resolution Earth surface images.
