About
The μDragonfly Bus is a compact, flight-proven microsatellite platform designed for Earth observation missions requiring a very high level of stability. At just over 100 kg, it offers a robust platform that supports high-performance payloads while maintaining a modular design, making it well-suited for scalable satellite constellations. With EOSSAT-1 as its first mission, the μDragonfly Bus supports demanding remote sensing applications with robust power systems, precise attitude control, a high degree of agility and an architecture optimised for rapid integration and responsive operations. Built to balance performance, reliability, and cost-efficiency, the μDragonfly Bus is ideal for operators seeking proven, scalable solutions that reduce time to orbit without compromising mission success.
