µDragonfly Bus

The Dragonfly Aerospace µDragonfly Bus is designed to provide stable and precise Earth-imaging capability across a range of spectra. The system has an automated Attitude and Orbit Control System (AOCS) including a Xenon electric propulsion unit. Communication is enabled via an X-band data downlink and S-band TMTC, and the bus includes various electrical interfaces for simple integration with a range of payloads. Attitude and Orbit Control • Pointing Control Stability → <0.0015°/sec (3-sigma) • Pointing Control Accuracy → <0.01° (3-sigma) • Slew Rate → Up to 4°/sec Communications • S-Band TMTC → 400 kbps down, 150 kbps up • X-Band Data downlink → 2.5 Gbps (Peak) Electrical Power System • Solar Array Peak Power → 220 W • Orbit Average Power (OAP) → 140 W Electrical Interfaces • TMTC → CANbus, RS422/RS485 • Data → LVDS / SpaceWire / SerDes Payload • Available Mass → Up to 100 kg • Available Volume → Ø500 mm x 1000+ mm
