KOMPSAT-5 (Korean Multi-purpose Satellite-5), also known as Arirang-5, is an South Korean observation satellite launched by Korea Aerospace Research Institute on August 22, 2013. It is a low-orbit satellite with an operational orbit of 550 km.
KOMPASAT-5 was developed with a total project cost of 238.1 billion won from June 2005. The Ministry of Science, ICT and Future Planning, the Ministry of Trade, Industry and Energy, etc. jointly initiated the project, and related industries such as the Korea Aerospace Research Institute, Korea Aerospace Industries, Korean Air, Hanwha, Doosan Heavy Industries, and Satrec Initiative participated in the development. [1]
It is the first South Korean satellite to be equipped with a synthetic-aperture radar, making it an all-weather Earth observation satellite that can precisely observe the Earth in high resolution even in bad weather such as cloudy days and at night. Its operational orbit is 550 km. [1]
While the existing KOMPSAT-2 and KOMPSAT-3 use visible light and they cannot observe the ground on dark nights or cloudy days, KOMPSAT-5 is equipped with a SAR uses microwaves and can penetrate clouds. [1]
Development was completed in 2010, but its launch was delayed for over two years. It was finally launched into space from the Yasny launch base at 8:39 p.m. (11:39 p.m. KST) on August 22, 2013, and successfully made its first contact with the Troll Satellite Station approximately 32 minutes after launch. [2] 1 hour and 27 minutes after launch, it successfully established communication with the ground station in Svalbard, Norway, and 5 hours and 56 minutes later (5:36 a.m. KST), it successfully established its first communication with the ground station at the KARI Satellite Information Research Center in Daejeon, confirming the success of the launch. [1]
Its main mission is to observe the Korean Peninsula twice a day, day and night, from an altitude of 550 km, to monitor disasters such as marine oil spills and volcanic eruptions, and to build a Geographic information system. It can obtain photos with a resolution of up to 1 m when calibrated. [1]
As of August 2018, It has orbited the Earth approximately 27,000 times over five years, communicated with ground stations 7,000 times, and provided over 127,000 photos through a total of 58,440 shots. In particular, the images provided in disaster situations such as floods, droughts, wildfires, earthquakes, and marine oil spills were evaluated to be of great help in rapid response, and images were also provided to various public and private services related to public safety and land and resource management. [3]
It was originally launched with a mission life of 5 years and the goal of operation until August 22, 2018. However, in August 2018, a review committee formed by the Ministry of Science and ICT and the KARI conducted a technical inspection and determined that additional mission performance was possible, extending the operation period by 2 years.

The Korea Aerospace Research Institute, established in 1989, is the aeronautics and space agency of South Korea. Its main laboratories are located in Daejeon, in the Daedeok Science Town. KARI's vision is to continue building upon indigenous launch capabilities, strengthen national safety and public service, industrialize satellite information and applications technology, explore the Moon, and develop environmentally-friendly and highly-efficient cutting-edge aircraft and core aerospace technology. Current projects include the KSLV-2 launcher. Past projects include the 1999 Arirang-1 satellite. The agency was founded in 1989. Prior to South Korea's entry into the Institute for Advanced Engineering (IAE) in 1992, it focused primarily on aerospace technology. As of May 2024, KARI is an affiliated research institute of the Korea AeroSpace Administration.
Naro-1, previously designated the Korea Space Launch Vehicle or KSLV, was South Korea's first carrier rocket, and the first South Korean launch vehicle to achieve Earth orbit. On January 30, 2013, the third Naro-1 vehicle built successfully placed STSAT-2C into low Earth orbit.
The Naro Space Center is a South Korean spaceport in South Jeolla's Goheung County, operated by the state-run Korea Aerospace Research Institute.
Maspalomas Station is an INTA-operated, ESTRACK radio antenna ground station for communication with spacecraft located at the southern area of Gran Canaria island, on the INTA campus. It is situated on the Montaña Blanca hill and is visible from the coastal resort of Meloneras, close to Maspalomas. It was originally established in the 1960s to support NASA's nascent human spaceflight program.
KOMPSAT-1, also known as Arirang-1, was a satellite created by the Korea Aerospace Industries (KAI) and Korea Aerospace Research Institute (KARI), and launched by a United States launch vehicle on 21 December 1999. This was the first satellite built primarily by South Korean engineers, although previous foreign-built satellites had been launched by Korean companies. It took its name from the popular Korean folk song Arirang.
KOMPSAT-2, also known as Arirang-2, is a South Korean multipurpose Earth observation satellite. It was launched from Plesetsk Cosmodrome, Russia at 07:45:43 UTC on 28 July 2006. It began to transmit signals at 14:00 UTC the same day. Like the earlier KOMPSAT-1 satellite, it takes its name from the popular Korean folk song Arirang. Its launch was the culmination of a project begun in 1995.
KOMPSAT or Korean Multi-Purpose Satellite is a series of South Korean multipurpose satellite for Earth observation, communications, meteorological, environmental, agricultural, and oceanographic monitoring applications.
KOMPSAT-3, also known as Arirang-3, is a South Korean multipurpose Earth observation satellite. It was launched from Tanegashima Space Center, Japan at 16:39 UTC on 17 May 2012. Like the earlier KOMPSAT-1 and KOMPSAT-2 satellites, it takes its name from the popular Korean folk song Arirang. Its launch was the culmination of a project begun in 1995.
STSat-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.
STSat-2B, or Science and Technology Satellite-2B, was a South Korean satellite which was lost in the failure of the second flight of the Naro-1 launch vehicle. It was to have been operated by the Korea Aerospace Research Institute (KARI), and was intended to demonstrate technology for future spacecraft. The satellite had a mass of 100 kg (220 lb), and was expected to operate for at least two years.
Nuri, also known as KSLV-II, is a three-stage launch vehicle, the second one developed by South Korea and the successor to Naro-1 (KSLV-1). Nuri is developed by Korea Aerospace Research Institute (KARI). All three stages use indigenously developed launch vehicle engines, making Nuri the first indigenously developed South Korean orbital launch vehicle.
The South Korean space program began in earnest in the 1980s when research on space development began. Korea Aerospace Research Institute was established in October 1989, and the Korea AeroSpace Administration was established in May 2024.
