About
The ηDragonfly is a nano-class satellite bus that revolutionises space delivery with the capability to deploy multiple satellites in a single launch. It combines microsatellite performance and reliability within compact cubesat-class parameters, eliminating the need for additional launcher pods. Weighing just 50 kg, the ηDragonfly is engineered to deliver five years or more of in-orbit operation and is designed for sensitive imaging payloads. It leverages validated avionics components from the successful EOS SAT-1 satellite mission launched in January 2023, ensuring top-tier performance and reliability. The bus features a fully automated AOCS (attitude and orbit control system) capable of target tracking, with high pointing control stability (<0.005°/sec, 3-sigma) and pointing accuracy (<0.01°, 3-sigma), a slew rate of up to 12°/sec, geolocation knowledge accuracy of 120 m (3-sigma), and a 10 Hz control frequency. Propulsion is provided by a xenon electric propulsion system delivering 11 mN thrust at up to 1400 s specific impulse. Communications include S-band TMTC (400 kbps downlink, 150 kbps uplink) and X-band data downlink at up to 2.6 Gbps peak. The power system provides 113-197 W solar array peak power, 71-125 W orbit average power (OAP), and up to 1.2 kW peak power, on an unregulated bus voltage of 24.3-32.4 V, with up to 20-70 W OAP available for payloads. Available mass for payloads is up to 50 kg within an available volume of 450 × 450 × 400 mm. TMTC interfaces include CANBus, RS422/RS485, and GigE, while data interfaces include LVDS, SpaceWire, and SerDes. An optional High Speed Data Recorder (HSDR) with 1 TB capacity is available.
