ηDragonfly Bus
High-performance imaging satellite
The cutting-edge ηDragonfly is a nano-class satellite that revolutionises space delivery with the capability to deploy multiple satellites in a single launch. The ηDragonfly combines microsatellite performance and reliability within the compact cubesat-class parameters, eliminating the need for additional launcher pods.
Weighing just 50 kg, ηDragonfly is engineered to deliver five years or more of in-orbit operation and is designed for sensitive imaging payloads. Leveraging validated avionics components from the successful EOS SAT-1 satellite mission launched in January 2023, ηDragonfly ensures top-tier performance and reliability.
