[AP Satellite Participates in KRW 9.5 Billion Onboard Computer Development for GEO-KOMPSAT-5]

AP Satellite (KOSDAQ: 211270) announced on June 26 that it has secured a KRW 9.5 billion contract to participate in the development of the onboard computer (OBC) for the GEO-KOMPSAT-5 geostationary meteorological and space weather satellite.

Under the contract, AP Satellite will develop and deliver the satellite's onboard computer (OBC) for GEO-KOMPSAT-5, which will operate in geostationary orbit approximately 36,000 km above Earth to monitor weather and space weather across the Korean Peninsula and the broader Asian region. The contract runs from June 2026 through May 21, 2028.

The GEO-KOMPSAT-5 development program is a next-generation, privately led satellite project with a total budget of KRW 666.8 billion, spanning from 2025 to 2031. The project is commissioned by the Korea Meteorological Administration (KMA) and the Korea AeroSpace Administration (KASA), with LIG D&A serving as the lead developer for the satellite system, spacecraft bus, and meteorological payload.

As part of the project, AP Satellite will be responsible for developing the Engineering Model (EM) for onboard computer verification, the Flight Model (FM) to be installed on the satellite, the Software Test Bed Model (STBM) for flight software development and testing, and the STB EGSE (Electrical Ground Support Equipment) used for testing and control.

The onboard computer serves as the satellite's central processing unit, integrating and controlling onboard subsystems while processing mission data. It performs critical functions including attitude control, orbit correction, and communications with ground stations.

GEO-KOMPSAT-5 is Korea's third meteorological satellite and the country's first privately led geostationary meteorological satellite. Scheduled for launch in 2031, it will provide continuous 24-hour weather observation, space weather monitoring, and early detection of hazardous weather events.

An AP Satellite representative stated, "Building on our experience from the development of GEO-KOMPSAT-2A and GEO-KOMPSAT-3, we will leverage our expertise in developing key satellite avionics for the GEO-KOMPSAT-5 program. Drawing on our extensive experience in geostationary satellite development, we will continue to strengthen our position in the expanding private space industry."
