Key highlights
The Dawn Aerospace CubeDrive propulsion Modules are turn-key propulsion modules designed for CubeSats. It is available in 0.8U, 2U, and 4U forms.
It utilizes nitrous oxide (N2O) and propylene (C3H6). These green propellants are widely available with low costs and lead times from domestic suppliers.
The system also includes thrusters, tanks, tubing, health monitoring, control electronics, and structures. It consists of one B1 thruster and has the capability to deliver multiple avoidance maneuvers for large satellites.
