CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.
