Sentinel-1D is the last satellite of the first generation of the Copernicus radar mission.
When fully operational, Sentinel-1D will enhance AIS observations for improved vessel identity, location, and direction of travel tracking.
Sentinel-1D carries advanced radar to supply all-weather, day-and-night imagery.
Sentinel-1D will incorporate state-of-the-art radar technology to provide accurate images of the Earth's surface in adverse weather conditions, both day and night.
The Sentinel-1D satellite is equipped with advanced radar technology.
The Sentinel-1D satellite will enter a sun-synchronous orbit at 693 km.
The Sentinel-1D satellite will be placed into Sun-Synchronous Orbit (SSO) at an altitude of approximately 693 km (≈430 miles).
ESA's European Space Operations Centre (ESOC) has been conducting simulations for Sentinel-1D, scheduled for launch on 4 November 2025.
Sentinel-1D and Sentinel-1C are equipped with C-band synthetic aperture radar (SAR) instruments.
Sentinel-1D is part of the Copernicus Earth observation program and will deliver high-resolution radar images of Earth's surface.
Once operational, Sentinel-1D will join Sentinel-1C in orbit to ensure continuity and reliability of Copernicus radar imaging services.
The C-band SAR instruments on Sentinel-1D and Sentinel-1C can capture detailed surface imagery regardless of cloud cover or light conditions.
Sentinel-1D will deliver radar images of Earth’s surface.
The advanced radar instrument on Sentinel-1D provides all-weather day-and-night imagery of Earth's surface.
The Sentinel-1D satellite is designed to carry an advanced radar instrument.
Sener designed and manufactured the deployment and locking mechanism for the synthetic aperture radar (SAR) instrument on the Sentinel-1D satellite.
Sentinel-1D features advanced radar technology that allows for imaging of the Earth's surface in any weather conditions, day or night.
Sener has participated in the development of the Sentinel-1D satellite, which is scheduled to launch on November 4 from French Guiana aboard an Ariane 6 rocket.
Sentinel-1D is based on the PRIMA platform developed by Thales Alenia Space for the Italian Space Agency (ASI).
Leonardo supplied attitude sensors (Autonomous Star Tracker) and radar power units for Sentinel-1C and -1D.
