The South Korean
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.
