Positioning

CesiumAstro is a US maker of active phased-array communications (antennas, beamforming, and processing integrated into flight-ready terminals) supplying the SDA Proliferated Warfighter architecture, with multi-orbit and 5G NTN product lines. It deepened vertical integration by acquiring RF-chip designer Jariet Technologies (August 2026), owning the silicon under its arrays, and raised $626M total (a $270M Series C in February 2026), though its platform-level Element demo has not yet flown. Revenue is estimated at 10-100m and hinges on the 2025-27 launch schedule.
