Other systems

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 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.

XFS

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