VACCO’s Propulsion System Controller is optimized for SmallSats and CubeSats and is a fully integrated controller including several driver types for many configurations of valves, heaters and pressure transducers.
The controller can be used with a blowdown system or a pressure regulated system. It comes pre-installed with a pressure regulation algorithm which allows a normally closed valve to regulate pressure. This allows an elegant yet effective way for pressure regulation of green mono-propellants, hydrazine, cold gas or other systems.
This radiation tolerant controller heavily leverages components with flight heritage and TID and SEE testing to provide a robust controller package. The aluminum housing can easily be customized to provide additional radiation shielding. Flight heritage exists with NanoACE in LEO and two MarCO units flown by Mars. Flight proven from LEO (NanoACE) to Mars (MarCO) and beyond.
