South Korea successfully launched a precision aviation satellite on Thursday to improve the accuracy and reliability of global positioning system (GPS) signals and better ensure flight safety, the government said.

The satellite of the Korea Augmentation Satellite System (KASS), the country’s first precision GPS location augmentation system, lifted off from the Guiana Space Center in Kourou, French Guiana, at 6:50 a.m. Thursday (Seoul time), according to the Ministry of Land. , Infrastructure and Transport.

The satellite was successfully separated from the rocket at approximately 7:18 a.m. after separations of the fairing and the rocket’s first stage.

For KASS, South Korea leased Malaysia’s MEASAT-3d communications satellite for 15 years.

The system can improve the GPS position error to 1.0-1.6 meters from the current level of 15-33 meters in real time to ensure the reliability of information throughout the country.

The government plans to launch a pilot service around December before full operation next year, according to the ministry.

South Korea is the seventh country to have a geosynchronous satellite system officially registered with the International Civil Aviation Organization (ICAO), after the United States, the European Union, India, the Japan, Russia and China.

The country has been developing KASS since 2014 to meet international standards and adapt to the country’s topography and environment, according to the Korea Aerospace Research Institute.

The researchers said they plan to develop aviation satellites with the country’s own technologies by 2035, highlighting the current heavy reliance on foreign technologies. (Yonhap)
