Neumann Space

Plasma propulsion for your mission

Introducing the revolutionary Neumann Thruster – a highly adjustable, efficient and scalable in-space electric propulsion system for satellites. Whatever your mission, we have a solution.

Mission Capability

Our product range creates value for our customers in all space operations and travel. For example our thruster can fulfil all requirements for Low Earth Orbit (LEO) mission profiles such as extending mission lifetimes, station keeping, orbit raising, constellation phasing, inclination changes, de-orbiting and more.

More value for your mission

Higher fuel efficiency means more satellite operational capability and mission manoeuvres

More mass for your mission

Less propellant mass means higher payload mass fraction and longer mission lifetime


Due to the pulsed operation of the system, you can use as little or as much power as you want without losses in specific impulse.

More scalability for your mission

Easily scalable fuel quantity (Mass and volume) – can simply add more fuel modules or a larger fuel rod without increasing system complexity.

The Neumann Thruster

Our product is a lightweight solar-electric ion thruster. It uses our patented Centre-Triggered Pulsed Cathodic Arc Thruster (CT-PCAT) technology to convert a solid conductive fuel rod into plasma and produce thrust. The system can use a range of conductive fuels giving a level of control over propulsion performance like never seen before. It offers the ability to generate high specific impulse levels and provide exceptional ∆v.

Product Features

Scalable to satellite size and mission

Each thruster unit is customisable in terms of power, fuel type and quantity with or without multiple propulsion systems

Highly adjustable thrust frequency

Control every pulse triggering and duration, fire less or more often as needed

Highly adjustable specific impulse

Ability to choose from a range of conductive fuels options based on required mission performance up to specific impulse of over 10,000 seconds

Low power pulsed operation

Pulsed operation permits low voltage input at low power levels to have the same efficiency as higher powered systems

High Jet Power Efficiency

Ability to make jet power efficiency trade-offs based on the chosen fuel from 50-95%

Exhaust geometry control

Narrow exhaust plume divergence. Dense and efficient propellants allow more payload volume.

Small form factor

Store additional fuel more efficiently than any other system on the market

Simple, reliable propellant management

No tanks or pipes needed, no exhaust neutraliser, no moving parts, no electrostatic grids
