Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission's Sentinel-2A and Sentinel-2B satellites were joined in orbit in 2024 by a third, Sentinel-2C, and in the future by Sentinel-2D, eventually replacing the A and ...
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.
Sentinel-2B is a European optical imaging satellite that was launched on 7 March 2017. It is the second Sentinel-2 satellite launched as part of the European Space Agency 's Copernicus Programme , and with its orbit phased 180° against its sister satellite, Sentinel-2A .
Sentinel-2A, B, and C Active ESA: 2015 Constellation of three, each satellite carries MSI sensor for high spatial resolution imaging. Part of the Copernicus Programme. Sentinel-3A and B Active ESA: 2016 Constellation of two, each satellite carries sensors OLCI and SLSTR. Slightly coarser spatial resolution and more spectral bands than Sentinel-2.
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
It is also expected that one of the sentinel satellites will test a new experiment with regards to weather prediction. As a part of its payload, it will use Global Navigation Satellite System Radio Occultation (GNSS-RO), a method to detail changes and information of different layers in the atmosphere. [18]
The European Data Relay System (EDRS) system is a European constellation of GEO satellites that relay information and data between satellites, spacecraft, UAVs, and ground stations. The first components (a payload and dedicated GEO satellite) were launched in 2016 and 2019.
The Satellite Data System (SDS) is a system of United States military communications satellites. At least three generations have been used: SDS-1 from 1976 to 1987; SDS-2 from 1989 to 1996; SDS-3 from 1998 to the present. It is believed that these satellites were known by the code name Quasar. [1]
