These high-resolution images have been used for various applications such as surveillance of massive natural disasters, utilization of natural resources, construction of geographic information systems (GIS), and cartography [6]. The purpose of the KOMPSAT-3 project was to develop the third very high-resolution (VHR) imaging satellite with high agility. It also aims to improve the national capabilities of the satellite development as well as to broaden the core knowledge and hardware building infrastructure required to race with world leading companies or nations in space development. The development of KOMPSAT-3 began in 2004, and the satellite was launched using the H-IIA launch vehicle of Mitsubishi Heavy Industries (MHI) in Japan on May 18, 2012. It operates in a sun-synchronous orbit for 4 years with a 28-day repeat ground track at a nominal altitude of 685 km. KOMPSAT-3 is now providing very high resolution imagery of 0.7 m in panchromatic and 2.8 m in multispectral bands and supporting various public and civilian applications [7]. The KOMPSAT-3A satellite currently under development aims to provide high-resolution infrared (IR) and electrooptical (EO) images. The spatial resolution is 0.55 m in the panchromatic band, 2.2 m for the multispectral bands and Figure 2. KOMPSAT-2 satellite. Figure 3.
