Launch Overview
On December 1, 2025, Arianespace successfully launched the KOMPSAT-7 (KOrea Multi-Purpose SATellite-7) from Europe’s Spaceport in Kourou, French Guiana. The launch occurred at 12:21 p.m. EST (1721 GMT; 2:21 p.m. local time) aboard a Vega C rocket, marking the sixth mission for this rocket type. Approximately 44 minutes post-launch, the satellite was deployed into a sun-synchronous orbit (SSO) at an altitude of 576 kilometers (358 miles) above Earth.
Satellite Specifications and Purpose
The KOMPSAT-7 satellite, weighing 3,990 pounds (1,810 kilograms), is designed to enhance South Korea's Earth observation capabilities. Developed by the Korea Aerospace Research Institute (KARI), it serves as the successor to KOMPSAT-3A, which was launched in March 2015. The satellite features advanced optical data transmission technology, enabling real-time processing of large volumes of Earth-observation imagery. This capability is crucial for meeting the increasing demand for high-quality satellite imagery from governmental and institutional users in South Korea.
Technical Innovations
KOMPSAT-7 incorporates several technological advancements, including the Advanced Earth Imaging Sensor System – High Resolution (AEISS-HR) payload and a control management gyroscope for improved maneuverability. Notably, it is equipped with an onboard computer that is over three times faster than its predecessors, significantly enhancing attitude control performance. The satellite's ground image processing system utilizes advanced parallel processing techniques, allowing for rapid geometric correction and imagery generation within 15 minutes of data receipt.
Arianespace's Role and Statements
David Cavaillolès, CEO of Arianespace, expressed pride in supporting South Korea's ambitious national space program through this launch. He noted that this mission marks the fourth satellite launched for KARI by Arianespace. The successful deployment of KOMPSAT-7 is expected to significantly bolster South Korea's Earth observation capabilities.
Launch Success Rate
The Vega C rocket has now completed six launches, with five being successful. The only failure occurred during its second mission in December 2022. Arianespace's VV28 mission is part of a broader effort to enhance satellite capabilities for various applications, including environmental monitoring and disaster management.
What's Next for KOMPSAT-7
Following the launch, KARI confirmed successful contact with the satellite via the Troll Satellite Station in Antarctica. KOMPSAT-7 is anticipated to begin providing ground observation images in the first half of 2026, further contributing to South Korea's strategic objectives in space exploration and Earth monitoring.
