KompSat-2 satellite
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.
Technical characteristics of the spacecraft KompSat-2
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.
Technical characteristics of onboard survey equipment
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.
