The GEOStar is a family of satellite buses designed and manufactured by Northrop Grumman Innovation Systems. The family started focused on small geostationary communications satellites. The first iterations focused on the sub-5 kW commercial segment that was left vacated after the retirement of the HS-376 satellite bus. It started with the STARBus on CTA Space Systems, which was later bought successively by Orbital Sciences, Orbital ATK, and most recently Northrop Grumman Innovation Systems.[1][2]
