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.
