Sentinel-1A is due for decommissioning at the end of the month after Sentinel-1D was fully commissioned in May following its launch in November 2026.
Sentinel-1A launched in 2014 and Sentinel-1B launched in 2016.
The first-generation Sentinel-1 constellation began with the launch of Sentinel-1A in 2014.
Sentinel-1D will replace Sentinel-1A after an overlapping operational phase.
Sentinel-1D will replace Sentinel-1A, which has been operational for 11 years.
Sentinel-1D will replace Sentinel-1A when fully commissioned.
The Sentinel-1D replaces Sentinel-1A, which has been operational for 11 years, exceeding its planned lifespan.
Once fully commissioned, Sentinel-1D will replace Sentinel-1A, which has remained operational for four years beyond its expected seven-year lifespan.
Sentinel-1A will be decommissioned and begin a several-year deorbiting process.
The Sentinel-1D satellite will replace the Sentinel-1A, which has been operational for 11 years.
Sentinel-1C currently operates with Sentinel-1A to deliver radar images of Earth’s surface in all weather conditions, day and night.
Sentinel-1A was the first satellite in the series and was launched in April 2014.
The launch of Sentinel-1D will provide a replacement for Sentinel-1A, which has been in orbit for 11 years.
Sentinel-1A has exceeded its intended lifespan after 11 years in orbit, and Sentinel-1D will take over its role in maintaining mission coverage and data continuity.
The launch of Sentinel-1D will replace Sentinel-1A, which has been in orbit for almost 11 years.
ESOC has successfully commissioned and operated ten satellites under the Copernicus Earth Observation program since the launch of Sentinel-1A in April 2014.
Sentinel-1C joins Sentinel-1A, which has been operational since 2014 and is expected to be replaced by Sentinel-1D in 2025.
The Sentinel-1 series began with Sentinel-1A, launched in April 2014, followed by Sentinel-1B in 2016.
Copernicus has been using data from Sentinel-1A and from other synthetic aperture radar spacecraft while awaiting Sentinel-1C.
The first post-earthquake Sentinel-1A image was taken on February 9, 2023, followed by another image on February 10, 2023.
