TunaCan Thruster
The most compact resistojet for Small Satellites and CubeSats
► High thrust
► Safe & Green
► Low power consumption
The TunaCan propulsion unit is the only system in the market that can be entirely installed in the “tunacan” volume available in many CubeSat deployers, which is located outside the main CubeSat structure. With a very compact size and low power consumption, the system is specially designed for 3U and 6U CubeSats.
Support all your satellite needs
Constellation management
Position and maintain each satellite of your constellation.
Satellite life extension
Extend your satellite lifetime to maximize your mission ROI.
Orbit optimization and maneuvers
Optimize your satellite orbit after launch.
Collision avoidance
Raise or lower your satellite orbit to avoid collisions with other space objects.
De-Orbit
De-orbit your satellite at the end of your mission to avoid space debris and international penalties.
Ideal for 1U – 6U

Typical Applications
Propulsion capabilities are essential nowadays to efficiently deploy and operate CubeSat constellations, however, they are also necessary to maintain altitude on very low orbit missions and avoid collisions with other space objects. Please take a look at the application examples for the 400 km orbit:
For 3U (5kg)
| Product | Total Impulse | Life-time | Orbital Change | Orbit Phasing | Collision avoidance |
|---|---|---|---|---|---|
| No Propulsion | 0 Ns | 1.6 years | No | No | No |
| TunaCan | 200 Ns | 4.3 years | ±70 km | 0° to 360 | Yes |
| TunaCan + 1U | 1000 Ns | 15.4 years | ±340 km | 0° to 360 | Yes |
For 6U (10kg)
| Product | Total Impulse | Life-time | Orbital Change | Orbit Phasing | Collision avoidance |
|---|---|---|---|---|---|
| No Propulsion | 0 Ns | 1.6 years | No | No | No |
| TunaCan | 200 Ns | 3 years | ±35 km | 0° to 360 | Yes |
| TunaCan + 1U | 1000 Ns | 8.3 years | ±170 km | 0° to 360 | Yes |
