Flexible and high-thrust electric propulsion systems

ExoMG™ is a family of high-thrust and flexible electric propulsion systems suited for all mission needs for satellites ranging from 5 kg to 1.000 kg. Whether you are looking to deploy a constellation, change the altitude or inclination of your spacecrafts, perform a RAAN phasing, maintain your orbit or avoid collisions, ExoMG™ will meet your needs.

Demonstrated, flight-proven solutions

Superior thrust for earlier revenues

Built-in flexibility with our modular approach

Versatile solution for all different missions

Why choose ExoMG™

The propulsion system adapts to your platform, not the opposite, with limited non-recurring effort.

The total impulse is configurable and can be modified using a different tank form factor.

We use a reliable space-proven technology: Hall Effect Technology (HET). ExoMG™ has been validated in space and have been delivered worldwide.

Smallsats have a limited lifetime. The sooner they get to the operational orbit, the higher the effective time they can generate revenue

Technology

A Hall Effect Thruster (HET) is an ion thruster in which electrons emitted by a cathode are trapped in a magnetic field, and used to ionize a propellant – thereby creating a plasma into the discharge channel.

The plasma is then accelerated to produce thrust, thanks to an electric field created between the anode and the cathode.

The Hall Effect Technology has been used for decades and equips most of the large satellites thrusters, because it combines the high impulse of electric propulsion technology along with a very high thrust-to-power ratio.

Due to unique innovations on the anode, the cathode, and the fluidics system we manage to reduce the size of this technology to fit it in small satellites.
