COSMO-SkyMed (COnstellation of small Satellites for the Mediterranean basin Observation) is an Earth-observation satellite space-based radar system funded by the Italian Ministry of Research and Ministry of Defence and conducted by the Italian Space Agency (ASI), intended for both military and civilian use. The prime contractor for the spacecraft was Thales Alenia Space. COSMO SkyMed is a constellation of four dual use Intelligence, surveillance, target acquisition, and reconnaissance (ISR) Earth observation satellites with a synthetic-aperture radar (SAR) as main payload, the result of the in

Gonets (Russian Гонец, for Messenger) is a Russian civilian low Earth orbit communications satellite system. It consists of a number of satellites, derived from Strela military communications satellites. The first two satellites, which were used to test and validate the system, were launched by a Tsyklon-3 launch vehicle from the Plesetsk Cosmodrome on 13 July 1992, and were designated Gonets-D. The first operational satellites, designated Gonets-D1, were launched on 19 February 1996. After launch, the first three satellites were given military Kosmos designations, a practice which was not con

ICEYE Ltd. (natively ICEYE Oy) is a Finnish microsatellite manufacturer and operator. ICEYE was founded in 2014 and is now the world's largest synthetic aperture imaging radar constellation.

SkySat is a constellation of sub-meter resolution Earth observation satellites owned by Planet Labs, providing imagery, high-definition video and analytics services. Planet acquired the satellites with their purchase of Terra Bella (formerly Skybox Imaging), a Mountain View, California-based company founded in 2009 by Dan Berkenstock, Julian Mann, John Fenwick, and Ching-Yu Hu, from Google in 2017.

BRITE-Constellation is an ongoing space mission carrying out two-band photometry in wide fields with a constellation of six (presently, three operational) BRIght Target Explorer (BRITE) nanosatellites. The mission was built by a consortium of three countries, Canada, Austria, and Poland, each operating two BRITE satellites. The six satellites were launched into low-Earth orbits between February 2013 and August 2014. Each satellite is a cube-shaped spacecraft with sides of hosting an optical telescope of aperture feeding an uncooled CCD with a field of view of approximately 20° × 24°. The satel
