Copernicus Programme

programme of the European Commission

Sentinel-1 is the first of the Copernicus Programme satellite constellations for Earth observation operated by the European Space Agency (ESA). Data collected via the satellites are used e.g. for marine and land monitoring, emergency response to environmental disasters, and economic applications.

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 B satellites, respectively. The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space A

Sentinel-3 is an Earth observation heavy satellite series developed by the European Space Agency as part of the Copernicus Programme. As of 2024, it consists of 2 satellites: Sentinel-3A and Sentinel-3B. After initial commissioning, each satellite was handed over to EUMETSAT for the routine operations phase of the mission. Two recurrent satellites, Sentinel-3C and Sentinel-3D, will follow in approximately 2026 and 2028 respectively to ensure continuity of the Sentinel-3 mission. thumb|305x305px|Model of Sentinel-3 Each Sentinel-3 satellite is designed to operate for seven years in a sun-synchr

Earth observation satellite

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. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. It provides information for agriculture and forestry, among other services, allowing for prediction of crop yields.

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 detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used.

Sentinel-2A is a European optical imaging satellite launched in 2015. It is the first Sentinel-2 satellite launched by the European Space Agency's and this Sentinel is part of the European Commission's Copernicus Programme. The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands. Its observations support services such as forest monitoring, land cover change-detection, natural disaster management and water quality monitoring. On 7 March 2017 the Sentinel-2A was joined in orbit by its sister satellite, Sentinel-2B.

Earth observation satellite

Sentinel-4 is a series of European Earth observation missions supporting the EU Copernicus Programme. It is the first project to monitor European air quality from geostationary orbit. Sentinel-4 focuses on monitoring of trace gas concentrations and aerosols in the atmosphere to support air-quality near-real time applications, air-quality monitoring, and climate monitoring – specifically with a short revisit period over Europe.
