STSat-2C, or Science and Technology Satellite-2C, or Naro Science Satellite (ko:나로과학위성) was a South Korean satellite which was launched in 2013. It was operated by the Korea Aerospace Research Institute (KARI), and was intended to demonstrate technology for future spacecraft. The satellite had a mass of , and was expected to operate for less than a year.

SAC-D (, meaning Satellite for Scientific Applications-D), also known as Aquarius after its primary instrument, was an Argentine Earth science satellite built by INVAP and operated by CONAE. SAC-D was launched from Vandenberg Air Force Base in the U.S. on 10 June 2011, with a planned mission life of five years. Due to a power system failure, the mission was ended on 8 June 2015.

Sich-1 was the first Ukrainian Earth observation satellite and was launched on 31 August 1995 at 06:49:59 UTC by Ukrainian Tsyklon-3 rocket from Plesetsk Cosmodrome in Russia. It operated until 2001.

TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is a German twin satellite mission using interferometric synthetic aperture radar (InSAR). It is developed in a public-private partnership between the German Aerospace centre (DLR) and EADS Astrium (now Airbus Defence and Space). It consists of the original TerraSAR-X satellite (TSX) and an identical spacecraft (TDX) in formation flying, with typical distances between 250 and 500 m. The two satellite constellation allowed the generation of the WorldDEM global digital elevation models starting in 2014.

Jason-3 is a satellite altimeter created by a partnership of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and National Aeronautic and Space Administration (NASA), and is an international cooperative mission in which National Oceanic and Atmospheric Administration (NOAA) is partnering with the Centre National d'Études Spatiales (CNES, French space agency). The satellite's mission is to supply data for scientific, commercial, and practical applications to sea level rise, sea surface temperature, ocean temperature circulation, and climate change.

STSat-2A (Science and Technology Satellite-2A) was a satellite launched by the Korea Aerospace Research Institute (KARI), the national space agency of South Korea, from the Naro Space Center in Goheung County, South Jeolla using the Naro-1 (KSLV-1) launch vehicle.

Lapan- TUBSat is Indonesia’s first remote sensing satellite, made by the experts from National Institute of Aeronautics and Space (Lembaga Penerbangan dan Antariksa Nasional, Lapan) and Technische Universität Berlin (TUB) Germany. The uses of the satellite are for Indonesian natural resources observation and weather forecast for the Indonesian area. Lapan-TUB Sat was launched aboard PSLV-C7 on 1 January 2007 from the Indian space centre in Sriharikota and still functioning well after the fifth birthday.

French/Italian Earth observation satellite programme

MMSAT-1 (also known as Lawkanat-1) was a Burmese microsatellite launched to the International Space Station (ISS) on 20 February 2021 and deployed into orbit from the ISS on 22 March 2021. It was Myanmar's first microsatellite and jointly built by Japan's Hokkaido University and Myanmar Aerospace Engineering University. It was delivered to the ISS by the American cargo spacecraft Cygnus NG-15. MMSAT-1 was temporarily held on ISS and its deployment was delayed due to the 2021 Myanmar coup d'état. It was deployed into orbit on 22 March 2021.

Diwata-1 also known as PHL-Microsat-1 was a Philippine microsatellite launched to the International Space Station (ISS) on March 23, 2016, and was deployed into orbit from the ISS on April 27, 2016. It was the first Philippine microsatellite and the first satellite built and designed by Filipinos. It was followed by Diwata-2, launched in 2018.
