South Korea’s geostationary satellite

In December of 2018, South Korea launched the first geosynchronous satellite COMS 2A that was independently developed by the country.
The satellite was carried by Arianespace's Ariane 5 launched at the French Guiana Space Center in South America.
At this point, South Korea became the eighth country in the world to possess geosynchronous orbit satellite technology.

Previously, only 7 countries had this technology: the United States, the European Union, Japan, India, China, Russia and Israel.

South Korea began developing the COMS 2A satellite in July 2011, and it took over 7 years to finally successfully launch the satellite.

COMS 2A is used for meteorological observation.
The satellite entered the geosynchronous transfer orbit 25 minutes after liftoff, completed satellite-rocket separation 34 minutes later, and achieved its first remote communication with the Australian Tangala ground station 39 minutes later.  
COMS 2 satellite project is composed of two "twin" satellites.
COMS 2A is a geostationary meteorological observation satellite.
It will always stay over the Korean Peninsula and conduct 24-hour real-time and precise monitoring of typhoons and other meteorological disasters.
COMS 2B, launched in February of 2020, is an environmental monitoring satellite.

The environmental sensors it carries will accurately measure nitrogen dioxide, sulfur dioxide, ozone and other atmospheric pollutants that form fine dust or cause climate change within 10 years.

Some sources would identify COMS 1, launched in 2010, as the first  geosynchronous satellite of Korea, by other standards.
It is worth noting that that the life of COMS 1 will be extended by 2 years to 2020.

Subsequently, South Korea developed and launched its first military geosynchronous communications satellite in 2020.  
The U.S. Space Exploration Technology Company (SpaceX) used "Falcon 9" to launch South Korea's first military satellite Anasisi-II, from Cape Canaveral Air Force Station.

in Florida.
South Korean military sources said that after the successful launch of "Anasisi-II", the combat execution capabilities of the South Korean army are expected to be greatly enhanced.
