AP Satellite operates around two pillars: a satellite communication segment and a satellite manufacturing segment. The satellite communication segment sells mobile terminals using Thuraya's geostationary satellites from the United Arab Emirates, and it accounted for 60.9% of revenue on a 3Q25 cumulative basis.
The satellite manufacturing segment designs and develops onboard computers (OBC), high-speed data recorders/processors (SDR), and electrical ground support equipment (EGSE), covering the remaining 39.1%.
The company has won and developed national space projects including the Korean satellite navigation system, geostationary public-purpose communication satellites, and standard onboard computers for next-generation medium satellites.
Within the domestic satellite manufacturing ecosystem, roles are divided by component and payload stage: AP Satellite holds the largest domestic delivery track record in onboard computers, SDR, and EGSE, while SAR and optical payloads are mainly handled by Hanwha Systems, and SAR sensors plus communication/radar systems by LIG Nex1.
These firms often form subcontracting or consortium relationships on the same programs. The communication segment has maintained sole-vendor status with key customers for more than 20 years, with SoC design capability based on the ETSI GMR-1 standard acting as a technical barrier to entry.
The K-LEO consortium, launched in February 2026, includes Hanwha Systems, LIG Nex1, Korea Aerospace Industries, AP Satellite, and Satrec Initiative, illustrating the cooperative structure of Korea's satellite industry.
