About us
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. We’re hiring. Explore open roles at CesiumAstro.com/careers.

Today marks an important milestone for CesiumAstro. We’ve officially closed on nearly 270,000 square feet of advanced manufacturing space in Bee Cave, Texas, supporting the next phase of growth for our company. This expansion represents a $500 million investment over the next 5 years and will grow our Austin-area workforce to more than 1,000 employees by 2030. The facilities will support engineering, manufacturing, testing, and delivery of mission-critical space and defense systems—all under one roof. We’re proud to continue building the future of space infrastructure in Texas. Read more at the link in the comments.

Thomas H. Hand, Ph.D., and Cody Vaudrin, Ph.D., recently joined everything RF to discuss phased arrays, antenna architecture, and what it takes to deliver communications for space. As multi-disciplinary engineers, Tom and Cody contribute across RF, antenna design, DSP/FPGA, digital and mixed-signal electronics, embedded software, power electronics, mechanical engineering, test, and more, reflecting the technical depth that defines CesiumAstro. An integrated, system-level approach to engineering? That’s Hardware Over Hype. ▪️Link to the interview in comments.
