The four operational modes offered by Sentinel-1 are: [11] [16] [17] Strip Map (SM) Mode, which features 5-by-5-metre (16 by 16 ft) spatial resolution and an 80 km (50 mi) swath. The sole uses of SM are to monitor small islands as well as emergency management for extraordinary events upon request.

Sentinel-1A is a European radar imaging satellite launched in 2014. It is the first Sentinel-1 satellite launched as part of the European Union's Copernicus programme. The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions. It analyzes many phenomena occurring on Earth, from ...
Spatial resolution is defined as the pixel size of an image ... Sentinel-1 (SAR imaging), Sentinel-2 ... providing data for conservation managers to monitor ...
Sentinel-1B was a European radar imaging satellite launched on 25 April 2016. It is the second of two original satellites in the Sentinel-1 constellation, part of the European Union's Copernicus programme on Earth observation. The satellite carries a C-SAR sensor, capable of providing high-resolution imagery regardless of weather conditions.
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam
The sounder satellites carry the Infrared Sounder (IRS) and Ultra-violet Visible Near-infrared (UVN) instruments. UVN is part of the European Commission's Copernicus programme and fulfils the Sentinel-4 mission to monitor air quality, trace gases and aerosols over Europe hourly at high spatial resolution. Two MTG satellites - one Imager and one ...
Sentinel-3 is now one of the best equipped missions to map the ocean hosting a SAR altimiter, multispectral spectrometer a radiometer and several other instruments on multiple satellites with alternating orbits providing exceptional temporal and spatial resolution.
