A Sentinel-2 image of the island of South Georgia. Sentinel-2 serves a wide range of applications related to Earth's land and coastal water. The mission provides information for agricultural and forestry practices and for helping manage food security. Satellite images will be used to determine various plant indices such as leaf area chlorophyll ...
Sentinel-2A is a European optical imaging satellite launched in 2015. It is the first Sentinel-2 satellite launched as part of the European Space Agency 's Copernicus Programme . The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands.
The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters. The scalable modular architecture is shared with the long-range AN/TPY-4 radar, which has 1000 individually controlled elements and uses GPU computing for signal processing.
Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. [4] The mission was originally composed of a constellation of two satellites, Sentinel-1A and Sentinel-1B, which shared the same orbital plane. Two more satellites, Sentinel-1C and Sentinel-1D are in development.
A Sentinel-3 image shows true colour (left) and land temperature (right) during the 2021 Eurasia winter heat wave. SLSTR (Sea and Land Surface Temperature Radiometer) determines global sea-surface temperatures to an accuracy of better than 0.3 K (0.3 °C; 0.5 °F). It measures in nine spectral channels and two additional bands optimised for ...
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 ...
Sentinel-4 is a European Earth observation mission under development to support the European Union Copernicus Programme.It will focus on monitoring of trace gas concentrations and aerosols in the atmosphere to support operational services covering air-quality near-real time applications, air-quality protocol monitoring, and climate protocol monitoring.
An image viewer or image browser is a computer program that can display stored graphical images; it can often handle various graphics file formats. [1] Such software usually renders the image according to properties of the display such as color depth , display resolution , and color profile .
