100 kg class satellite bus designed for electro-optical imaging payloads. Flying on EOSSAT-1 (ZA-008, launched January 2023) as the first operational mission, carrying two DragonEye cameras at 178 kg total satellite mass. Accommodates up to 100 kg payload mass in a 500 mm diameter envelope. Solar array peak power 220 W, orbit average power 140 W, energy storage up to 600 Wh. X-Band data downlink 2.5 Gbps peak. Pointing stability <0.0015 deg/sec (3-sigma), pointing accuracy <0.01 deg (3-sigma), slew rate up to 4 deg/sec. Xenon electric propulsion for orbit maintenance. Design life 5 years. Three units can launch side-by-side in a 2.2 m payload fairing.
uDragonfly Bus is a 100 kg class satellite bus for electro-optical imaging payloads.[1] eoPortal identifies EOS SAT-1 as flying a uDragonfly bus with two DragonEye cameras after its January 2023 Falcon 9 Transporter-6 launch.[2]
The bus accommodates payloads in a 500 mm diameter envelope, but public materials give three payload-capacity figures: 60 kg in 2021 product-launch coverage, 70 kg in the SatCatalog specification block, and 100 kg in the SatCatalog overview.[3][1] Published power figures include 220 W solar-array peak power, 140 W orbit-average power, and up to 600 Wh of energy storage.[1]
The platform specification gives 2.5 Gbps peak X-band downlink, pointing stability below 0.0015 deg/sec, pointing accuracy below 0.01 deg, slew rate up to 4 deg/sec, xenon electric propulsion for orbit maintenance, a five-year design life, and side-by-side launch accommodation for three units in a 2.2 m payload fairing.[1]
