Satellites in low Earth orbit

The International Space Station (ISS) is a space station in low Earth orbit (LEO). It is the product of the International Space Station program and is operated by five partner space agencies: NASA, Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It is the first space station built, maintained and crewed through international cooperation and the largest human spacecraft ever constructed. It is an orbital research station, where scientific experiments in microgravity are conducted and the space environment is studied. Since 2 November 2000, it has hosted the longest continuous presence of humans in space. Alongside Tiangong, it is one of the only two currently operational space stations.

Tiangong-1 () was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a crewed laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life.

Tiangong-2 () was a Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was launched on 15 September 2016. It was deorbited as planned on 19 July 2019.

TIROS-1 (or TIROS-A) was the first operational weather satellite, the first of a series of Television Infrared Observation Satellites (TIROS) placed in low Earth orbit.

Envisat ("Environmental Satellite") is a large Earth-observing satellite which has been inactive since 2012. It was launched on 1 March 2002 aboard an Ariane 5 from the Guyana Space Centre in Kourou, French Guiana, into a Sun synchronous polar orbit at an altitude of 790 ± 10 km.

Globalstar, Inc. is an American telecommunications company that operates a satellite constellation in low Earth orbit (LEO) for satellite phone, low-speed data transmission and Earth observation. The Globalstar second-generation constellation consists of 25 satellites.

The GEOSAT (GEOdetic SATellite) was a U.S. Navy Earth observation satellite, launched on March 12, 1985 into an 800 km, 108° inclination orbit, with a nodal period of about 6040 seconds. The satellite carried a radar altimeter capable of measuring the distance from the satellite to sea surface with a relative precision of about 5 cm. Its 18-month initial phase was a classified Geodetic Mission with a near-23-day repeat that was intended to replicate the orbit of the short-lived Seasat. After this, the satellite was maneuvered into a near-17-day exact repeat for oceanographic research

Kanopus-V-IK (formerly Kanopus-V 2) is a Russian Earth observation satellite developed by the All-Russian Scientific Research Institute of Electromechanics and operated by Roscosmos. It was launched on July 14, 2017, designed for monitoring the environment over a large swath of land, and has an expected service life of 5 years.
