KOMPSAT-5 (Korean Multi-purpose Satellite-5), also known as Arirang-5, is a 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]
Technology
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]
