Kleos Space is a space enabled, activity-based intelligence, data as a service company based in Luxembourg, US and UK. Kleos Space aims to guard borders, protect assets and save lives by delivering global activity-based intelligence and geolocation as a service. The first Kleos satellite system, known as Kleos Scouting Mission (KSM) was succesfully launched in November 2020 and will deliver commercially available data and perform as a technology demonstration. KSM will be the keystone for a later global high-capacity constellation. The second cluster of Kleos satellites, Polar Vigilance Mission (KSF), succesfully launched in June 2021 under a rideshare contract with Spaceflight Inc. The KSF1 satellites were launched into a 500-600km Sun Synchronous orbit, increasing Kleos’ coverage to the north and south of the 37 degree inclination of the Scouting Mission satellites.
