Utilization of Satellite Images

High value-added satellite information for public safety and improvement of quality of life

Utilization of Satellite Images [image]

Satellite images are utilized in a wide range of areas and applications such as national land management, natural disaster monitoring, marine resource management, agriculture and forestry, environmental weather observation, and national security to create huge added values.

The world satellite image market was worth around USD 1.7 billion in 2015, and is expected to steadily grow to the size of around USD 3.0 billion in 2025.

Korea generates around 100,000 pages of satellite images annually from observation satellites, such as the low-orbit multipurpose satellite series and the geostationary satellite Cheollian. In 2016, more than 5,900 images were distributed to the private sector as well as government agencies and organizations through the satellite information utilization council.

Satellite images have thus far generated an economic effect far in excess of the actual cost of satellite development, as proven by the import-substitution effect of KRW 557.8 billion of Multi-purpose Satellite 2, which completed its mission in 2015 after being launched in 2006.

The Multipurpose Practical Satellites Nos. 3, 3A and 5, in particular, generate outstanding satellite image assets such as sub-meter class (70cm and 55cm class) high-resolution satellite images and radar-IR images, which are leading the global market for commercial satellite images.

Satellite images also help to enhance the status of Korea in the international community.

KARI joined the International Charter on Space and Major Disasters in 2011 and is now providing satellite data to help international efforts to detect major disasters and analyze damages as part of its provision of satellite data for application humanitarian programs worldwide. 

  • National Satellite Operation & Application Center

    The Center is dedicated to the operation of government satellites and the systematic and efficient utilization of satellite data.

    It manages the satellite data generated by government satellites and conducts the development of cutting-edge satellite operating technology and R&D utilizing satellite data.

    Korea has obtained ultra-precision optical images, synthetic aperture radar (SAR) images and infrared (IR) images generated by the Multipurpose Practical Satellites Nos. 3, 3A and 5, which are currently operating at low orbit. It has also attained and is applying exclusive weather and marine observation images generated by the Cheollian satellite operating in geostationary orbit.

    The National Satellite Operation & Application Center plans to upgrade the satellite data distribution and utilization system, and promote the satellite data utilization service to facilitate the use of government satellite data in public and private sectors.

    To that end, it will develop an integrated database and platform to integrate the government’s satellite data and increase its added value by establishing a user-friendly data distribution function to contribute to national economic development.

Satellite Operation Building

The Satellite Operation Building has the function of monitoring and controlling satellites, such as monitoring the status of Multipurpose Satellites and the Cheollian satellite and transmitting commands to them. It plans satellite missions based on the requests of agencies that use satellite images and transmits commands to satellites to carry out their missions.

More specifically, it has the job of monitoring the function and performance of satellite systems; planning the operation of satellite systems; making decisions on satellite system orbit and position control and the prediction, adjustment and management of orbit; monitoring communication between the satellite system and the ground system; and receiving earth observation images and weather images.

A 13m S-band antenna and 7.3m X-band antenna have been installed at the center in Daejeon, while tracking centers have been installed at Jeju Island, at the Sejong Base in the South Pole, and at Weno Island in Micronesia.
