Other systems

The SPS40 Propulsion System was designed for medium and large satellites and able to adjust the orbit parameters and insure the maneuverability of satellites in space.

The SPS25 Propulsion System was designed for mini satellites mass up to 500 kg.

The ST40 Hall Thruster with an anode layer is designed for use as part of the propulsion system for satellites mass up to 1 T.

The ST25 Hall Thruster is a modification of a Thruster with an Anode Layer.


SETS is developing a modular Xenon Feed System (XFS) with significant reductions in mass and cost while increasing system reliability.
