CesiumAstro creates compact and efficient communication systems specifically for space applications. Their products, such as the Nightingale Series and CommPack, are designed to be small and scalable, meeting the industry's standards for Size, Weight, Power, and Cost (SWaP-C). The Nightingale Series offers a complete system with a small form factor, while the CommPack serves as a low-profile communications payload. Additionally, they provide products like the SDR-1001, a compact software-defined radio, the SBC-1461, a credit-card-sized single-board computer, and the PCU-1C28, a high-efficiency DC-to-DC converter. CesiumAstro differentiates itself from competitors by focusing on modular hardware and software that can be easily integrated for mission-specific configurations, catering to clients like NASA. Their goal is to provide affordable, mission-ready communication solutions by leveraging the latest semiconductor and manufacturing technologies.
