PM400 Series Propulsion Module

The PM400 is a bi-propellant propulsion module for 6-12U CubeSats. It allows manoeuvres of up to 230 m/s to be performed utilizing the non-toxic propellants nitrous oxide and propane in a self-pressurizing configuration.

Low system complexity and zero propellant toxicity allow for simple and robust operations, both on the ground and when in orbit. The medium tank pressure and high storage density of liquid propellants enables high safety factor tanks to be used with little mass penalty.

The standard configuration with a 2U propulsion module can be configured to suit any CubeSat structure and features an I²C or RS422/RS485 compliant interface.

Through the use of additive manufacturing, the system is highly customizable. Design parameters such as total system delta-V, interface style and thrust direction can be changed on request and adapted to an existing CubeSat architecture.

The PM400 can be seamlessly integrated with the iADCS400 to provide a fully integrated GNC and ADCS solution.
