KompSat-3, 3A satellites

The South Korean KompSat-3 spacecraft was launched on may 17, 2012 from Japan’s Tanegashima cosmodrome by an h-2A-202 launch vehicle into a sun-synchronous orbit of 685 km, with an inclination of 98.13 degrees. The KompSat-3 satellite was developed By the Korean aerospace Research Institute KARI (Korea Aerospace Research Institute) with the participation of Korean Air Lines Co., Korea Aerospace Industries Ltd., Doowon Heavy Industrial Co and Hanwha, as well as by EADS Astrium GmbH

In development of the new device was invested 286.6 billion Korean won or 252 million dollars. In total, South Korea plans to place five satellites with similar functionality in orbit.
Kompsat - 3A, identical to Kompsat-3, launched on 26.03.2015.
The KompSat-3 spacecraft consists of a payload-an AEISS (Advanced Earth Imaging Sensor System) camera and a satellite platform that takes it into space. The height of The KompSat-3 spacecraft is about 3.5 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 4.7 and 6.9 m. the mass of the KompSat-3 spacecraft in the refueled state is about 1000 kg.

Technical characteristics of the spacecraft KompSat-3, 3A:

According to the Ministry of science and technology of South Korea, the satellite will provide the opportunity to obtain accurate weather data, information on atmospheric fronts and weather over the ocean. The authorities also say that the device can be used for monitoring in case of natural disasters,as well as environmental monitoring.
