Sentinel-1
Sentinel-1 is a key component of the European Space Agency's (ESA) Copernicus programme, designed to provide valuable and reliable radar imagery for Earth observation. This radar satellite constellation consists of two identical satellites, Sentinel-1A and Sentinel-1B, working together to enable continuous and all-weather imaging of the Earth's surface.
Sentinel-1's primary mission is to acquire synthetic aperture radar (SAR) data, offering a unique perspective for monitoring various aspects of the Earth. SAR technology enables imaging of the Earth's surface regardless of weather conditions, daylight, or cloud cover, ensuring the acquisition of critical data under any circumstances.
Satellite details:
- Instrument: C-Band Synthetic Aperture Radar
- Resolution: 10m (Interferometric Wide Swath mode, IW), 40m (Extra Wide Swath mode, EW)
- Revisit time: Less than 5 days using both satellites, less than 3 days for asc/desc and overlap using both satellites
