SPS-40 propulsion system

The SPS-40 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 propulsion system is designed for advanced satellites constellations in order to correct position relatively to each other.

SPS-40 is based on two ST-40 Hall Thrusters.

The SPS-25 Propulsion System was designed for mini satellites mass up to 500 kg.

The ST-40 Hall Thruster with an anode layer is designed for use as part of the propulsion system for satellites mass up to 1 T.

The ST-25 Hall Thruster is a modification of a Thruster with an Anode Layer.


The Power Processing Unit is one of the components of the SPS-40 and SPS-25 propulsion systems.


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