Celesium Capital

CesiumAstro builds and delivers space communications systems—at scale.

We design, engineer, and manufacture software-defined radios, phased array payloads, and fully integrated satellites that enable real-time, multi-beam, multi-user connectivity across space-based and airborne networks.

Our systems are built for mission-critical applications and designed to adapt on orbit.

As a vertically integrated manufacturer, CesiumAstro brings RF, digital processing, and satellite integration together under one roof, enabling rapid production, consistent performance, and repeatable delivery.
