초록

Recently, there have been the World Economic Forum's space economy guidelines, the International Telecommunication Union's regulations for each satellite orbit, the development of chips using satellite communication by global manufacturers and service providers, and the registration of key telecommunication businesses. Accordingly, trends in low-orbit 5G satellite communication services in Korea were investigated and analyzed, and the current situation in Korea was diagnosed. Korea's satellite communications accounts for 0.31% of all satellites when analyzed centering on countries with 20 or more satellites. Korea's communication satellite holdings are insufficient compared to 187 times that of the United States, 45 times that of Russia, and 18 times that of China. There is no link technology between 5G and LEO, and the cost of launch vehicles is high. In addition, it is judged that the ecosystem of equipment companies in the low-orbit 5G-NTN business model is insufficient.
