our product


Simple, Versatile and Cost Effective propulsion systems to provide mobility to satellite platforms and nanosatellite deployers providing up to 1 mN of thrust.


Low cost

The system is specifically conceived to represent a trade-off between costs and performances, targeting a substantial cost reduction respect to currently available high-delta V units.

A 1.5+ Unit Cubesat
shape overall system

The system is conceived for satellite platforms requiring high delta-V (typically in the range from 6U up to 150 kg of mass, 20 – 60 W of power). It is built following the box-all-in-one concept on which PPU, PCU and thruster occupy an overall 1.5+ Unit Cubesat volume. Propellant tank and FCU are integrated at the top of the system occupying a volume which depends on system requirements.

Long life time

Thanks to its architecture, with no exposed electrodes and neutralizer the system is capable of long life time also in case of oxygen rich environment (low orbit). The motor itself is very versatile in term of mission profile, putting no limitation on restart capabilities, and allowing throttling if necessary.

Robust technology

The system can work with many different gases (CO2, Argon, Xenon, Iodine and others) making it adaptable to different mission scenarios and future customers’ needs.

Standard interfaces
with the satellite platform

The REGULUS motor interfaces with the satellite using CAN BUS or i2C is suitable for an easy integration.

Intense knowledge
of plasma production
and acceleration physics

Intense knowledge of the system behavior resulting in reduced/limited risks for flight systems development. Capability to translate customers’ specific needs of system scaling to cover different power and thrust level requirements, in limited time and costs.


Continuous Drag Compensation, Orbit raising, Orbital plane changes, Decommissioning of mini and micro platforms which can deliver 20 to 60 W power.


The motor, on different versions, is under development since 2008. Since then more than 10 Laboratory units and one Engineering model have been developed and tested. Extensive thrust measurements have been performed. Currently comparison test in other Electric Propulsion facility are scheduled and a final qualification unit is under development.


REGULUS is under development and it will be qualified in Q4 2019. An In-Orbit Demonstration mission is planned for 2020.

OUR background

We are working on magnetically enhanced RF plasma technology propulsion systems since more than 10 years. Starting from the sketch, we designed, manufactured and tested our plasma systems, solving the stoppers for its maturation.

We develop vacuum chambers combining different diagnostics and thrust balances for RF thruster testing.

Thruster technology

Magnetically enhanced RF plasma
thruster technology

The system is based on Magnetically enhanced RF plasma concept, which is peculiar for its physics comprehension complexity and engineering implementation simplicity.

Immersed electrodes free and neutralizerless

The thruster is characterized by a very simple structure: a dielectric cylindrical ionization chamber (discharge chamber), a radio-frequency (RF) antenna, a gas injection system, a magnetic system for plasma confinement (within the chamber), an outlet diaphragm and a plume screen.
The propellant is first ionized by means of the RF antenna and then expanded within the magnetic nozzle. The system does not present electrodes immersed in plasma and since it ejects a neutral plasma, it doesn’t require a neutralizer, simplifying the fluidic section and the PPU section.
The thruster eject plasmas into space thus doesn’t require neutralization systems. Moreover, it doesn’t implement grids or electrodes exposed to plasmas, thus allowing a very high life time.

Our technology

We have developed an innovative type of antenna system in order to allow better coupling and easier matching in space applications.

Our Technology is patent pending.
