Dawn’s unique and in-house developed chemical propulsion has been designed from inception to be a simple, effective propulsion system for satellite builders. It is modular and highly scalable to suit satellites of all sizes and total impulse requirements; from 500 - 250,000+ N.s. It is space-proven and has been previously launched by SpaceX, VEGA and Soyuz-2, on both CubeSats and 200 kg class satellites.
By utilising nitrous oxide and propene propellants in a self-pressurising configuration, this green propulsion architecture has increased capabilities compared to hydrazine, LMP-103S (ADN), AF-M315E (HAN) or other proprietary fuel-blend systems.
These points are unique to Dawn:
- Self-pressurizing propellants: No helium pressurisation systems required. This enables simple, lightweight and low-cost feed system and tank designs. Stable pressure throughout the satellite’s life ensures constant thrust and Isp of >285 s.
- Commonly available propellants: They can be sourced from local industrial gas suppliers and are not subject to export control restrictions.
- Electric based ignition: No preheating of catalysts results in significant power savings. It also means thrusters are rapidly cold-start capable, with unlimited cold-start capability.
- Thrusters fire in both ambient and vacuum environments: Combined with non-toxic propellants, this allows for simple satellite integration and highly representative hardware testing at system level with live or simulated propellants without the need for specialised testing environments.
- Thrusters operate in both hot and cold-gas modes: This means the same thruster can perform both high-performance burns and fine impulse manoeuvres.
- Low power draw: with an average firing power of 12.5W per thruster while firing.
- 6 DOF capable: through a fully integrated RCS system.
Dawn can deliver complete turn-key propulsion systems, complete with thrusters, propellant tanks, feed system and thruster control electronics. A full-service partner, Dawn provides support in hardware, logistics, systems integration, propellant sourcing and onsite fueling.
Dawn will go the extra mile, so that you can too!
