SPS25 propulsion system

The SPS25 Propulsion System was designed for mini satellites mass up to 500 kg. The propulsion system is used to adjust the positions of satellites and deorbit them after the finish of their operational lifespan. A vital advantage of this propulsion system is the significantly smaller power consumption.

SPS25 is based on the ST25 Hall Thruster.

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 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.


The Power Processing Unit is one of the components of the SPS40 and SPS25 propulsion systems.


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