NAOS (National Advanced Optical System) is the space component of Luxembourg's governmental dual-use observation satellite system LUXEOSys (Luxembourg Earth Observation System). Its purpose is to provide high resolution images to national and international governmental and military organizations such as NATO. The 800 kg satellite is built by OHB Italia and is equipped with a very high-resolution optical camera with a ground reolution of 50 cm in an around 450 km high sun-synchronous orbit. It will have a operational life time of 7 years. Also on board the launch is Dhruva Space's LEAP-1; Planet's Pelican-3 and Pelican-4; and Exolaunch’s Acadia-6, FFLY-1, FFLY-2, and FFLY-3.
NAOS was lifted into orbit during the mission ‘Falcon 9 Block 5 | NAOS’, on board a Falcon 9 space rocket.
The launch took place on Aug. 26, 2025, 6:53 p.m. from Space Launch Complex 4E.
