About
CesiumAstro
Connect. Detect. Defend.
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.
Headquartered in Austin, Texas, with operations in Colorado, California, the United Kingdom, Germany, and Japan, CesiumAstro is building the communications infrastructure modern missions depend on.
