About
The Dragonfly Bus is Dragonfly Aerospace’s largest satellite platform, engineered to support more complex, power-intensive and data-intensive payloads. With a combined bus and payload mass of up to 400 kg, it offers increased continuous power delivery, volume, and system redundancy — ideal for missions requiring high data throughput, extended operational lifespans, or more power-intensive payloads such as Synthetic Aperture Radar (SAR). The bus is built with a modular design, enabling custom configurations and streamlined integration for commercial and institutional missions alike, delivering mission versatility, robust performance, and future-ready scalability.
