About the Company

CesiumAstro

Designs satellite communications hardware and software

CesiumAstro builds end-to-end space and airborne communications systems, combining hardware and software to connect satellites, UAVs, and ground stations. Its products include active phased array antennas, software-defined radios, and complete RF payloads that enable electronically steered links for inter-satellite communication, high-rate downlinks, lunar communications, and 5G/NTN networks. The company ships plug-and-play, commercially manufactured, full-stack systems designed to be flexible and cost-efficient, rather than bespoke one-off solutions. Its goal is to make space-based connectivity more accessible and adaptable across space, air, and ground networks for both government and commercial customers.
