The Power Processing Unit is one of the components of the SPS-40 and SPS-25 propulsion systems. It provides power conditioning and control for the Plasma Thrusters and the Xenon Feed System unit.
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.
SETS is developing a modular Xenon Feed System (XFS) with significant reductions in mass and cost while increasing system reliability.
