While others build a piece of the communications stack, CesiumAstro engineers the entire architecture. Its systems span antennas, radios, SATCOM, and satellites, all designed to work together or on their own. Every product is developed in-house, built vertically, and made to scale.

Since 2017, CesiumAstro has tackled the hardest problems in space connectivity. Its phased arrays, processors, and flight-ready spacecraft already support commercial and government missions across air, ground, and orbit.

What sets CesiumAstro apart isn’t just what it builds, but how: modular design, commercial components, and a delivery-first culture that skips traditional defense timelines.

At CesiumAstro, the stack is the product, the playbook, and the path forward. And it’s shipping now.
