Observer-1A Earth Observation Cubesat
Observer-1A
OVERVIEW
Nara Space's first satellite and the first commercial cubesat launched by a Korean company. The 16U (20 x 20 x 40 cm), roughly 24 kg spacecraft carries a multispectral electro-optical camera with 1.5 m native resolution from a 525 km orbit, improved to about 0.5 m with AI super-resolution, over a 14 x 40 km swath. Launched on a SpaceX Falcon 9 rideshare from Vandenberg on November 11, 2023 (local time), it was first of the 113 satellites on that flight to transmit data and has operated beyond its two-year design life. The same 16U bus flew again as GYEONGGISat-1 (Observer-1B) in November 2025, and the 12U BusanSat followed in May 2026. The Observer bus and its onboard AI underpin the company's ADD mock-satellite contract and the KRIT autonomous proximity-operations demonstrator due by 2030.
