At Exotrail, we believe the next step for small satellites is to embark fully-integrated and reliable thrusting systems. That is why we design the smallest Hall Effect Thruster (‘HET’) in the world. Our plug-and-play propulsion unit will enable you to control your Cubesats and enhance their performances.

But we want to think nanosatellites at the constellation scale, which is why we also develop a whole constellation management solution, from mission design to constellation operation, in order to make the best out of your small satellites and let you focus on what is important: your customers.

Nanosatellites: the future is now

CubeSats are tiny standardized satellite units with an edge length of 10cm (1U). They can be combined and attached to one another in order to embark specific technology: 2U, 3U, 6U, etc. They are launched by Space Agencies or private launchers as passengers to a bigger spacecraft. Dedicated CubeSats launchers are also under development.

In spite of their small size, CubeSats deliver. Their performances are being enhanced each year and soon, entire businesses will be building upon nanosatellite technology.


Global costs are 500 times cheaper compared to other conventional satellites.


Low-coast approach enables nanosatellites to be used in constellations, exceeding the performances of classical satellites.

Hall Effect Propulsion

Our team has designed the latest generation of Hall Effect Thrusters (HET). Although this technology has been mainstream in the field of space propulsion for roughly fifty years, it had never been made accessible for nanosatellites. Until now.

We have designed and built the smallest HET in the world. We have also implemented major technological advances to make it simpler, smaller and more reliable.

Turnkey solutions for constellation management

While embarking propulsion can significantly enhance your spacecrafts' capabilities, we would not want you to commit costly additional resources to manage your constellation. That is why we are not only building a thruster, but also designing a whole propulsion solution with constellation management services. Our team develops tools to make the best out of your satellites and maximise their possibilities.
