On the 18th, KT SAT held a vision declaration ceremony at the KT SAT Geumsan Satellite Center, marking its 50th anniversary, and announced that it would leap forward as a platform-based comprehensive satellite service company.
◇ Next-generation satellite Mugunghwa Satellite 6A targeted for 2024 launch
At the proclamation ceremony, KT SAT announced plans for the Mugunghwa Satellite 6A. Mugunghwa Satellite 6, launched in 2010, has an expected lifespan of 15 years and is scheduled to reach the end of its service life in 2025. Satellite 6A is the successor to Satellite 6. It is scheduled to be launched as early as 2024.
KT SAT plans to apply High Throughput Satellite (HTS) technology, which has a data transmission throughput more than 10 times greater than existing satellites, to 6A, and is considering equipping it with Software Defined Sat (S/W Defined Sat) technology, which allows for coverage changes even after launch.
When equipped with variable beam technology, beam coverage can be changed even after launch, enabling the provision of communication services in accordance with changing customer requests. It is also possible to install a transponder that will function as an auxiliary satellite for the Korean Advanced Sensor System (KASS).
◇ Transition to a satellite-based platform operator
KT SAT, which has previously viewed satellite communication as a complement to terrestrial networks and focused on providing relay services, announced at the declaration ceremony that it would leap forward as a satellite-based platform operator providing services and solutions to the communication blind spots of the ocean and space.
KT SAT has achieved an average annual growth of 20% in the MVSAT (maritime satellite communication) sector and secured a market share of over 70% in the domestic merchant shipping market. Based on this, the company plans to launch an integrated maritime platform in the first half of 2021. Once the integrated platform is established, various solutions currently provided—such as ship internet, email, CCTV, and ship operation management—can be combined with MVSAT and implemented on a single server.
In addition, leveraging the characteristics of satellites, it is expanding into overseas countries where wired communication is difficult. In particular, it is providing broadcasting and telecommunications services in Southeast Asia, which has many islands. KT SAT plans to expand its influence to regions such as the Arab world and Mongolia in the future.
◇ Providing services to 5G-underserved areas and mobile devices via satellite
KT SAT is researching technology for integrating satellites and 5G. Last November, together with the KT Convergence Technology Institute, it successfully developed technology to integrate commercial 5G networks with satellite communication networks. On the 15th, it established a satellite environment-based testbed at the Geumsan Satellite Center in collaboration with the KT Convergence Technology Institute.
Starting in the second half of the year, KT SAT will conduct a Korea-EU joint research project at the Geumsan Satellite Center testbed. Through this, they will carry out a task to link satellites with 5G terminals and plan to demonstrate video transmission via satellite 5G at the French Open tennis event next May.
When satellite and 5G interworking technology is commercialized, the bandwidth of the 5G network will be expanded. As a result, it is expected that seamless 5G services will be provided via satellite in overseas regions where it is difficult to build terrestrial networks, as well as in mobile devices such as vehicles.
◇ Participation in national projects such as KASS and Korean GPS
KT SAT is participating in the 'Korea Augmentation Satellite System (KASS)' project promoted by the Ministry of Land, Infrastructure and Transport.
Once KASS is established, the current GPS error of 30m will be reduced to 1m, requiring two geostationary satellites and a ground station system. KT SAT is currently manufacturing one KASS main satellite. It is scheduled to be launched in the second half of 2021, and pilot services are set to begin in 2022.
In addition, KT SAT plans to participate in national projects such as the Korea Positioning System (KPS) and public multi-purpose communication satellites.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK텔레콤이 3월 21일 서울 광화문 일대에서 열린 대형 K-팝 공연에 AI 기반 네트워크 운영 시스템을 처음 적용해 통신 품질을 관리했다고 밝혔다. 공연 전후 3시간 동안 모바일 데이터 사용량은 12.15TB로 직전 주말 같은 시간대보다 약 2배 늘었다. SK텔레콤은 AI 시스템 ‘A-One’을 활용해 5분 단위, 50m 단위로 트래픽을 감시하며 과부하 가능성에 대응했고, 임시 통신 시설과 현장 인력 운영도 병행했다. 밀집 행사와 외국인 이용 수요가 동시에 늘어나는 환경에서 AI 기반 자율 네트워크 운영의 현장 적용 가능성을 확인한 사례로 해석된다.
