Propulsion Unit for CubeSats (PUC) are complete, high-performance, and compact small-satellite propulsion solutions. The all-welded titanium bodies come fully integrated with all necessary propulsion subsystems, including microcontroller, power processing unit, micro-cavity discharge thruster, propellant valves, heaters, sensors, and software. PUCs achieve their high impulse, low-volume capability by employing CU Aerospace Micro-Cavity Discharge (MCD) propellant heating technology, high-density and self-pressurizing liquid propellants, and an optimized low-mass-flow nozzle. PUCs are software-configurable to operate over a wide range of power, thrust, and impulse levels. System set-points, system status, and firing telemetry are all accessible and configurable through an RS422 serial interface. PUCs may be customized to meet customer specific mission requirements. PUCs are available in package sizes as small as 0.25U.
