Korean Air said it carried out a successful test last month at the CAMTIC Institute of Technology in Jeonju, North Jeolla Province, involving a 5-meter-class antenna deployment system. The test was conducted as part of a defense core-technology project led by the defense technology institute, titled “Deployable large satellite-mounted antenna deployment system,” with participants from the institute, CAMTIC, Steplab and Korea Aerospace University, among others.
The key to the technology is minimizing volume at launch by storing the large antenna folded inside the launch vehicle, then deploying it to full size after reaching the target orbit. Because the antenna must deploy precisely without error in the space environment, the system is considered a major factor in determining satellite performance.
Korean Air said the test confirmed that a 5-meter satellite antenna deployment device operated as designed. The company said the results showed stable deployment while maintaining the antenna’s shape in extreme space conditions, resolved mechanical interference in the complex deployment structure, and maintained high precision through repeated deployment cycles.
Korean Air said the outcome also validated the effectiveness of its independently designed and manufactured “antenna deployment mechanism.” The company said it will use the test data to accelerate development of its final goal: a large antenna deployment system.
Korean Air said it will continue pursuing technologies for the future space era, including ultra-high-resolution Earth observation satellites capable of distinguishing objects as small as 10 centimeters on the ground and 6G satellite communications technology, and that it aims to play a key role in next-generation satellite development linked to national security.
“As a leading company in South Korea’s aerospace industry, we will continue to do our best to advance national space assets and help the country move toward becoming a major space power, based on the technological capabilities we have built,” a Korean Air official said.
