The imagery, acquired by KOMPSAT 3/3A can be obtained from SIIS (SI Imaging Services), which is an exclusive representative of the KOMPSAT constellation. Each product is provided as a specific set of data: pan + four multispectral or as four pansharpened bands. Image data processing levels:
KOMPSAT 3 is an Earth observation mission of Korea Aerospace Research Institute (KARI), funded by Ministry of Education, Science and Technology (MEST) within the Korean government space development program. The project started in 2004 to continue KOMPSAT-1 and KOMPSAT-2 missions and provide high-res satellite imagery for Geographical Information Systems (GIS) and the following applied fields: agriculture, environment, oceanography and natural disasters.
KOMPSAT-3 (Arirang-3) satellite was launched on the H-IIA system on May 17, 2012 from Tanegashima Space Center in Japan. KOMPSAT 3A (Arirang-3A) joined the mission on March 25, 2015. It was launched on a Dnepr-1 vehicle (RS-20) from the Jasny Dombarovsky launch site, Russia, to the lower than KOMPSAT 3 sun-synchronous orbit.
To meet the demand for high-resolution imagery from government, both satellites are equipped with a pushbroom imager, AEISS (Advanced Earth Imaging Sensor System), developed by KARI in cooperation with EADS Astrium GmbH, Friedrichshafen. It is delivering the highest resolution data among the cameras installed on domestic satellites and is capable of acquiring images with maximum spatial resolution of 50-70 cm.
Notwithstanding KOMPSAT 3’s capacity to deliver panchromatic optical images at a nominal ground sampling distance (GSD) of 70 cm, the next satellite was enhanced with thermal infrared sensor, therefore KOMPSAT-3A became a unique example of space technologies commercialization. It appeared to be the first satellite, equipped with two imaging systems where the AEISS was complemented with IIS (Infrared Imaging System). It operates within the MWIR (Mid-Wavelength Infrared) region of 3 – 5 µm at high spatial and thermal resolution. These temperature-sensitive IR sensors (IRS) can assist in monitoring of wildfires, volcanic and seismic activities as well as water currents and natural disasters.
