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. Its observations support services such as forest monitoring, land cover change-detection, natural disaster management and water quality monitoring. [4]
On 7 March 2017 the Sentinel-2A was joined in orbit by its sister satellite, Sentinel-2B.
Sentinel 2A was launched by the Vega VV05 rocket on 23 June 2015 at 01:52 UTC. The satellite separated from the upper stage 54 min 43 s after liftoff. [5]
The satellite captured its first image 100 hours after launch, covering a 290 km (180 mi) wide swath from Sweden through Central Europe to Algeria. [6] [7] : 8 Commissioning occurred in October 2015. [7] : 8
Between 20 and 23 January 2017 the spacecraft suffered a mission planning anomaly which resulted in loss of data from its instrument, the Multi-Spectral Imager. [8]
SPOT is a commercial high-resolution optical Earth imaging satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES in the 1970s and was developed in association with the SSTC and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. The SPOT system includes a series of satellites and ground control resources for satellite control and programming, image production, and distribution. Earlier satellites were launched using the European Space Agency's Ariane 2, 3, and 4 rockets, while SPOT 6 and SPOT 7 were launched by the Indian PSLV.
The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) is an intergovernmental organisation created through an international convention agreed by a current total of 30 European Member States.
Satellite images are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps.
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), the European Environment Agency (EEA), the European Maritime Safety Agency (EMSA), Frontex, SatCen and Mercator Océan.
Thales Alenia Space is a joint venture between the French technology corporation Thales Group (67%) and Italian defense conglomerate Leonardo (33%). The company is headquartered in Cannes, France.
Sentinel-1 is the first of the Copernicus Programme satellite constellations conducted by the European Space Agency. 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. Sentinel-1B was retired following a power supply issue on December 23, 2021, leaving Sentinel-1A the only satellite of the constellation currently operating. Sentinel-1C is currently planned to launch in the final quarter of 2024.
Sentinel-2 is an Earth observation mission from the Copernicus Programme that acquires optical imagery at high spatial resolution 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.
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 2025 and 2028 respectively to ensure continuity of the Sentinel-3 mission.
The Earth and Mission Science Division is a group of European Space Agency (ESA) staff mission scientists, contractors, research fellows, young graduates, trainees, and administrative staff working within the Climate Action, Sustainability and Science Department of the Directorate of Earth Observation Programmes. The Division is located at ESA's European Space Research and Technology Centre in Noordwijk, South Holland, The Netherlands.
PROBA-V, or PROBA-Vegetation, is a satellite in the European Space Agency's PROBA series. It was launched in 2013 with a predicted usable lifetime between 2.5 and 5 years.
SEOSat-Ingenio, was a Spanish project to produce a satellite capable of providing wide-field imagery ensuring a repeat cycle of 38 days at 2.5 metre panchromatic resolution and 10 metre colour resolution, from a Sun-synchronous polar orbit; it was Spain's first optical imaging satellite. The satellite was part of the Spanish Earth Observation Satellite program. The mission was funded by Spain's Centre for the Development of Industrial Technology (CDTI). SEOSat-Ingenio information was to be used by various Spanish civil, institutional or government users. However, under the Copernicus Programme of the European Union, it was also accessible to other European users, as well as to the Group on Earth observation of the Global Observing System of Earth.
The Cartosat is a series of Indian optical Earth observation satellites built and operated by the Indian Space Research Organisation (ISRO). The Cartosat series is a part of the Indian Remote Sensing Program. They are used for Earth's resource management, defence services and monitoring.
PRISMA is an Italian Space Agency pre-operational and technology demonstrator mission focused on the development and delivery of hyperspectral products and the qualification of the hyperspectral payload in space.
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-5 Precursor (Sentinel-5P) is an Earth observation satellite developed by ESA as part of the Copernicus Programme to close the gap in continuity of observations between Envisat and Sentinel-5. It was launched in October 2017, and has a design life of 7 years. The TROPOspheric Monitoring Instrument (Tropomi) provides the most detailed methane emissions monitoring available.
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.
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. The specific objective of Sentinel-4 is to support this with a high revisit time over Europe.
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.
The Sentinel-6 Michael Freilich (S6MF) or Sentinel-6A is a radar altimeter satellite developed in partnership between several European and American organizations. It is part of the Jason satellite series and is named after Michael Freilich. S6MF includes synthetic-aperture radar altimetry techniques to improve ocean topography measurements, in addition to rivers and lakes. The spacecraft entered service in mid 2021 and is expected to operate for 5.5 years.
