– Remarkably reducing GPS error information to the level of 1-1.6m, providing precise location information service throughout Korea from '23 –
□ The Ministry of Land, Infrastructure, and Transport announced on June 6 that it had “successfully launched the first aeronautical satellite” of the Korea Aerospace Satellite Service (KASS)* to provide precise location information services throughout the country.
* Korea Augmentation Satellite System (KASS): An international standard satellite navigation correction system that provides real-time location information from satellites by reducing GPS errors as a Korean aerospace satellite service.
– Accurate and highly reliable location information can be provided by correcting the existing GPS error (15~33m) to 1~1.6m through facilities such as aeronautical satellites and ground reference stations and central processing stations
ㅇ Aeronautical Satellite Unit 1* was launched from the Kourou Space Center** in Guiana, South America, at around 6:23 a.m. on June 6 (local time), and the satellite protective cover (pairing) was separated, After going through a process such as separation of the first stage rocket, it was successfully separated at around 50:6, about 22 minutes after launch, and the launch was finally successful.
* Overseas satellite rental (equipped with repeater for aviation satellite service in Miasat communication satellite in Malaysia)
** As it is located near the equator, it has optimal launch conditions such as low fuel consumption when launching satellites.
ㅇ The normally separated Aviation Satellite Unit 1 is expected to move to a geostationary orbit (approximately 12 km) after about 36,000 days, and is expected to provide services in earnest from '23 after passing the orbit landing and signal testing.
□ On this day, Minister of Land, Infrastructure, and Transport Won Hee-ryong visited the Satellite Control Room of the Aerospace Research Institute located in Daejeon and directly observed the live broadcast of the launch of Air Satellite Unit 1 and encouraged researchers and other related parties.
ㅇ Immediately after the successful launch of the satellite, he received the atmosphere of the site and expressed his gratitude to the field officials through a phone call with the head of the Aviation Satellite Service Business Division of the Korea Aerospace Research Institute who was at the launch site (Kuru Space Center, Guiana, South America).
□ At the same time, an “Aerospace Satellite Science and Technician Meeting” was held at the site that day, attended by researchers who participated in the development of KASS technology and businessmen in related industries.
ㅇ Researchers from Korea Aerospace Research Institute and Korea Electronics and Telecommunications Research Institute, who have been in charge of the development of aerospace satellite service (KASS), and KTsat Co., Ltd., said, “We have accumulated a lot of know-how in the KASS development process, “We plan to develop aeronautical satellite units 3, 35, and 3 by the end of this year.”
* (Korea Positioning System, '35) A Korean-style satellite navigation system jointly developed by related ministries to stably provide precise location (P), navigation (N), and time (T) information to the Korean Peninsula and annexed islands.
– In particular, the research team stated, “Localization of core technologies is urgently needed due to the high dependence on foreign technologies for key parts of satellite payloads such as wireless amplifiers and oscillators. and attention,” he said.
ㅇ At the meeting, officials from Hanwha Systems Co., Ltd., which is promoting the Urban Air Mobility (UAM) project, and Tmap Mobility, which provides navigation map service, also attended the meeting and expressed their expectations for the KASS service.
– A company official said, “UAM is essential for city navigation and autonomous flight system construction. I hope there will be,” he said.
ㅇ In addition, officials from private companies said, “The ability of a private operator to lead the global space industry, such as Space-X in the United States, is based on the country’s original technology and support, so that private operators can actively participate in national aerospace projects. Opportunities should be expanded,” he added.
□ Minister of Land, Infrastructure, and Transport Won Hee-ryong said, “Location information has had a profound impact on human life, including trade, industry, and intellectual property. I am very happy and thrilled as the minister of the relevant ministries because the foundation has been laid for me to do so,” he said.
ㅇ “Aeronautical satellite service (KASS) is expected to become a key infrastructure for various future industries as well as the mobility industry such as drones, UAMs, and autonomous vehicles. We will secure the reliability and safety of the aviation satellite service so that it can be used, and we will actively develop technology to advance the positioning technology.”
□ At the same time, Minister Won emphasized, “We must take a leap forward as a science and technology powerhouse through the localization of core technologies.”
ㅇ “The successful development of KPS and KPS-based aviation, which provide aeronautical satellite services with our technology by localizing aviation satellite payloads, etc. We will actively cooperate with related ministries, researchers, and private companies to provide satellite services.”
