KompSat-2 (Arirang-2) satellite was developed by engineers of the Korea aerospace Research Institute (KARI). Launch of the spacecraft into a sun-synchronous orbit with a height of 685 km with an inclination of 98.13° was carried out on July 28, 2006 from the Russian cosmodrome Plesetsk by carrier rocket "Rokot".

KompSat-2 spacecraft consists of a payload-a multispectral camera and a satellite platform that takes it into space. The height of The KompSat-2 spacecraft is about 2.6 m with a diameter of 2.0 m in the withdrawal configuration. With the deployed solar panels and x-band antennas, the height and length are respectively about 2.8 and 6.9 m. the weight of the KompSat-2 spacecraft in the refueled state is about 800 kg.

Kompsat-2 is designed to produce digital images of the earth's surface with a spatial resolution of 1 m in panchromatic mode and 4 m in multispectral mode. A distinctive feature of KOMPSAT-2 is a long continuous shooting time of up to 120,000 sq km (533 scenes) on a single turn. The satellite is also equipped with an onboard recording device capable of recording up to 15,000 sq km of survey.

Main cases of using data obtained from KompSat-2 spacecraft:

  • creating and updating topographic maps and plans up to 1: 10,000 scale;
  • creation of digital elevation models (DEM) of high accuracy;
  • engineering surveys for the construction of infrastructure transportation and production of oil and gas;
  • implementation of forest management works, inventory and assessment of forests;
  • inventory of agricultural land, creation of land use plans;
  • creation of city plans and schemes of territorial planning of municipal districts;
  • inventory and monitoring of transport, energy and information communications;
  • observations of natural disasters;
  • control over the use of natural resources;
  • conducting research in various fields.
