The Unfurlable Reflector 3 Meter from Airbus is a Space-Qualified Deployable CFRP Antenna Reflector engineered for high-performance Earth observation and satellite communication missions. Designed with a deployed diameter of 3 meters and a compact stowed configuration of approximately 1.1 meters, it enables large-aperture performance within constrained launch volumes. Operating across the 8–12 GHz frequency range, it delivers precise RF performance optimized for X-band applications. This advanced reflector features a contour accuracy of less than 0.5 mm RMS, ensuring exceptional surface precision required for high-resolution radar and communication payloads. 

With surface reflectivity exceeding 97% of aluminum, it provides RF efficiency comparable to solid reflectors while maintaining the mass and packaging advantages of a deployable structure. The scalable architecture supports multiple optical configurations, including apex-fed, Cassegrain, and Gregorian layouts, offering flexibility for diverse payload designs. The reflector incorporates a spring-driven deployment mechanism that eliminates the need for electric motorization, enhancing system reliability and simplifying spacecraft integration. 

A fully cold-redundant release and damping system ensures safe and controlled deployment in orbit, typically within 5–10 seconds. It achieves a first eigenfrequency of 28 Hz in stowed configuration and greater than 12 Hz when deployed, providing excellent structural stiffness and dynamic stability during launch and operational phases. Compact, lightweight and highly robust, the Unfurlable Reflector 3 Meter is ideally suited for Synthetic Aperture Radar (SAR) instruments, MEO data downlink missions and high-performance communication payloads requiring large deployable apertures with superior contour accuracy and RF efficiency across demanding space environments.
