Emerging from the Ecole Polytechnique and the CNRS

After 10 years of applied research and 2M€ already invested, we provide a breakthrough and game-changing propulsion solution the small satellite market is longing to embrace

Small satellites is the future

ThrustMe is a sub-system provider and service company developing and commercializing a patented space propulsion system for the next generation satellites

ThrustMe gives small satellites increased possibilities in space

We allow our customers, who are typically satellite integrators and actors in the small satellite market, to take full control of the orbit of small satellites enabling them to undertake amazing missions.

ThrustMe develops and commercialises breakthrough propulsion systems and added services. ThrustMe’s electric propulsion solution can provide the necessary thrust and high specific impulse to do high delta-V missions using only 5% of the satellite mass and volume, while still being able to carry out orbit transfers in just a few weeks. This is made possible by our patented technology allowing for extreme miniaturisation of the thruster with our smallest engine being 40% of the size of competitive ion thruster technologies yet having similar or even better performances. We provide a complete thruster module that fits into a one unit Cubesat, and we provide larger tailored engines for more advanced small satellites.

Ion thrusters are promising for SmallSats

BUT there are technological hurdles in miniaturization due to their need for a separate neutralizer and gaseous propellant – We solved this problem using clever, innovative solutions


In an ion thruster, ions from a gas discharge (a plasma) are accelerated via static electric fields using a set of biased grids. This ion beam generates thrust and its high velocity ensures a high Isp and therefore low propellant consumption. To avoid beam stalling and charging of the spacecraft, the positive ion beam needs to be neutralized by electrons in the downstream space. This is achieved with a separate neutralizer. Power, typically obtained from solar panels, is fed to the various parts of the system via a power processing unit (PPU). The propellant, typically xenon, is fed into the gas discharge chamber and the neutralizer.

Our solution is a novel ion thruster operating with solid propellant that combines technologies from the space and semiconductor industries. The acceleration grids are biased with radiofrequency (RF) voltages across a capacitor. Due to the different mass of ions and electrons the plasma acts as a diode and the capacitor charges up (self-biases). The resulting DC voltage accelerates ions continuously while electrons exit during a short period within the RF cycle. This leads to significant simplification and advantages over classical ion thrusters, while still keeping similar or even better performance. The use of a solid propellant with a high vapor pressure (such as iodine) removes the need for high pressure storage and complex valves for flow control.

ThrustMe's low power neutralizer-free ion thruster

Our patented solution solves a number of key problems

The Neutralizer
The neutralizer is a fragile and expensive element that is difficult to downscale due to both limitations in the minimum physical size and the minimum delivered electron current. In our technology we do not need one since both ions and electrons exit from the same plasma source.
Control of the space charge
The current from the ion beam (gas discharge) and the neutralizer is difficult to match and results in charging and ion back scattering. The capacitive nature of the acceleration system ensures equal currents of ions and electrons, completely removing problems related to charging
The Power Processing Unit
Power Processing Units (PPU) in classical systems are large, heavy and complicated due to the need for several DC amplifiers in both the gas discharge and neutralizer channels. Since we only use radio frequency power, the PPU is simpler and smaller because no High Voltage DC amplifiers are needed.
Gaseous propellant
Classical plasma based thrusters use xenon as the propellant gas. The cost of xenon is not such a problem for small systems, but both the plasma source and the neutralizer need complex and expensive gas flow regulation and the propellant is stored under high pressure in bulky containers. This is a large hurdle for miniaturization. We integrate solid iodine propellant in our system. Iodine has very particular properties. It has a very high vapor pressure sublimating directly from solid to gas. Therefore, it allows for the use of a simple storage container that can take any physical form and a simpler flow control system.
The thrust per area ratio is limited by the space charge limit (Child’s law), or in other words by the maximum current that can be extracted across a set of grids. Using radio frequency acceleration, the space charge limit is increased twofold, and translates into larger extracted currents. Therefore, the thrust can be doubled for the same size due to a higher space charge limited current.
Plume-satellite interactions
Plume-satellite interactions are reduced using radio frequency acceleration, compared to the classical acceleration methods, due to the directed emission of electrons and therefore a highly collimated beam.
