Summary

The Dragonfly Aerospace Dragonfly Bus is designed to provide accurate spatial resolution Earth imaging and mapping for a wide range of applications.

The system has a long lifetime and features an automated Attitude and Orbit Control System (AOCS) with a Xenon electric propulsion unit.

Communication is enabled via an S-band TMTC and an X-band data downlink, and the bus includes a variety of in-built electrical interfaces for simple integration with a range of payloads.

Applications

Designed for precise spatial resolution Earth imaging and mapping for a wide range of communication and scientific applications.
