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.
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.
Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit. A number of Earth-observing satellites, such as RADARSAT, have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth.
Cartosat-2 was an Earth observation satellite in a Sun-synchronous orbit and the second of the Cartosat series of satellites. The satellite was built, launched and maintained by the Indian Space Research Organisation (ISRO). Weighing around 680 kg at launch, its applications were mainly be towards cartography. It was launched by the Polar Satellite Launch Vehicle PSLV C7 launch vehicle on 10 January 2007.
SAOCOM is an Earth observation satellite constellation of Argentina's space agency CONAE. Two satellites are already orbiting the Earth in a Sun-synchronous orbit. The second one was launched on 30 August 2020.
China–Brazil Earth Resources Satellite 1 (CBERS-1), also known as Ziyuan I-01 or Ziyuan 1A, is a remote sensing satellite which was operated as part of the China–Brazil Earth Resources Satellite program between the China National Space Administration and Brazil's National Institute for Space Research. The first CBERS satellite to fly, it was launched by China in 1999.
Sentinel-1 is the first of the Copernicus Programme satellite constellation conducted by the European Space Agency. This 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 has been retired, leaving Sentinel-1A the only satellite of the constellation. The Sentinel-1 satellites carry a C-band synthetic-aperture radar instrument which provides a collection of data in all-weather, day or night. This instrument has a spatial resolution of down to 5 m and a swath of up to 410 km. The satellite orbits a Sun-synchronous, near-polar orbit. The orbit has a 12-day repeat cycle and completes 175 orbits per cycle.

PSLV-C37 was the 39th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program and its 16th mission in the XL configuration undertaken by the Indian Space Research Organisation (ISRO). Launched on 15 February 2017 from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh, the rocket successfully carried and deployed a record number of 104 satellites in Sun-synchronous orbits in a single mission, breaking the earlier record of launching 37 satellites by a Russian Dnepr rocket on 19 June 2014. This record was held until the launch of the Transporter-1 mission by SpaceX on 24 January 2021 which launched 143 satellites.
