The market for small satellites is growing fast, with the emergence of new players and new commercial offerings.

However, most current nanosatellite programmes are limited by the absence of onboard propulsion systems, leading to constraints on launch, operational performance, capacity for deorbit at the end of the satellite’s life etc.

The µ-PPI technology provides a complete, high-performance, miniature Hall-effect electric propulsion system (HET) able to respond to the unmet needs of these small satellites.


The simplicity of the new µ-PPI technology concept leads to a miniaturised electric propulsion system at a size compatible with nano and microsatellites.

The technology still inherits the robustness of HET engines, which have already proved themselves with older, larger satellites.

HET technology also offers more thrust than competing products, accelerating the satellite’s positioning in its operational orbit.


Thanks to their new thrust performance, nanosatellites can now contribute to new applications (communications, imaging) with the ability to carry out the necessary manoeuvres such as controlled deorbit, altitude and angle control, changes of orbit, link-ups, positioning and maintenance in satellite constellations, distant and potentially extraterrestrial missions etc.
