Sentinel-1 - Missions - Sentinel Online
The Sentinel-1 mission comprises a constellation of two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather.
Sentinel-1 will work in a pre-programmed operation mode to avoid conflicts and to produce a consistent long-term data archive built for applications based on long time series.
Sentinel-1 is the first of the five missions that ESA is developing for the Copernicus initiative.
For mission planning information, see the Observation Scenario pages.
The Sentinel-1 Mission Guide provides a high-level description of the mission objectives, satellite description and Ground Segment. It also introduces the related heritage missions, thematic areas, orbit characteristics and coverage, instrument payload and data products.
The Mission Guide categories are:
