etaDragonfly Bus is a 50 kg nano-class satellite bus positioned between CubeSats and microsatellites.[1][2] The platform uses a CFRP honeycomb composite structure and is described as providing microsatellite-grade attitude-control and communications performance in a compact bus.[1][2]
The bus accommodates payloads up to 50 kg through a 15-inch standard port.[1] Its published power figures are 113-197 W solar-array peak power, 71-125 W orbit-average power, and up to 300 Wh of energy storage.[1] Communications and pointing specifications include 2.6 Gbps peak X-band downlink, pointing stability below 0.005 deg/sec, pointing accuracy below 0.01 deg, and slew rate up to 12 deg/sec.[1]
SatCatalog lists CANBus, RS422/RS485, GigE, LVDS, SpaceWire, and SerDes interfaces, a five-year design life, and qualification against ECSS and NASA vibration, thermal-vacuum, and radiation standards.[1]
