*bus . products*

50 kg nano-class satellite bus bridging the gap between CubeSats and microsatellites. Delivers microsatellite-grade AOCS and communications performance in a compact CFRP honeycomb composite structure. Accommodates payloads up to 50 kg mass with a 15-inch standard port. Solar array peak power 113-197 W, orbit average power 71-125 W, energy storage up to 300 Wh. X-Band data downlink 2.6 Gbps peak. Pointing stability under 0.005 deg/sec (3-sigma), pointing accuracy under 0.01 deg (3-sigma), slew rate up to 12 deg/sec. Interfaces: CANBus, RS422/RS485, GigE, LVDS, SpaceWire, SerDes. Design life 5 years. Qualified to ECSS and NASA vibration, thermal vacuum, and radiation standards.

## Editorial
etaDragonfly Bus is a 50 kg nano-class satellite bus positioned between CubeSats and microsatellites.[^satcatalog-etadragonfly][^dragonfly-etadragonfly-announce] The platform uses a CFRP honeycomb composite structure and is described as providing microsatellite-grade attitude-control and communications performance in a compact bus.[^satcatalog-etadragonfly][^dragonfly-etadragonfly-announce]

The bus accommodates payloads up to 50 kg through a 15-inch standard port.[^satcatalog-etadragonfly] 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.[^satcatalog-etadragonfly] 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.[^satcatalog-etadragonfly]

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.[^satcatalog-etadragonfly]
