KT SAT Extends Satellite Lifespan, Eyes Low-Earth Orbit Expansion After 32 Years of Flawless Control

Nestled in the foothills of Yongin, South Korea, eight large dish antennas point skyward, a testament to 32 years of continuous satellite control. At the KT SAT Yongin Satellite Control Center, over 30 personnel meticulously monitor thousands of parameters for dozens of satellites, ensuring seamless communication links between Earth and space. Since opening in 1994, the center has operated without a single minute of downtime, managing South Korea's first communication satellite control center. It oversees five geostationary satellites, handling everything from status monitoring and orbit control to collision avoidance.

The center's extensive experience has cultivated deep expertise. Accumulated data on satellite aging and past anomalies allows for rapid identification of signal issues. Collaborating with the Electronics and Telecommunications Research Institute (ETRI), KT SAT has localized precise orbit prediction and analysis technology, reducing reliance on foreign systems. This capability was instrumental in extending the life of the Mugunghwa 6 satellite. Originally slated for decommissioning after its 15-year lifespan, KT SAT redeployed it to the Southern Hemisphere's Oceania market after transferring its domestic services to a new satellite. This involved a complex 180-degree attitude maneuver, transforming a satellite facing decommissioning into a valuable asset for a new business area.

Now, KT SAT aims to expand its control expertise from geostationary to low-Earth orbit (LEO) satellites. LEO constellations, with hundreds or thousands of satellites operating below 2,000 km, offer advantages like reduced communication latency and are crucial for non-terrestrial networks (NTN) in 6G communications. South Korea has identified LEO satellite communication networks as a future growth engine. KT SAT plans to leverage its accumulated experience and technology to secure LEO satellite operation capabilities. "With vast amounts of accumulated space data and experience from actual operations, we are recognized for our global-level control capabilities," said Choi Seong-ho, KT SAT's Executive Vice President of Technology. "We will apply this to future satellite technologies like LEO satellites and 6G non-terrestrial networks to showcase the high status of K-satellite technology worldwide."
