Integrated Thruster Unit (ITU) includes a high-precision thruster orientation mechanism (TOM) and two propulsion systems based on the stationary plasma thruster with a nominal discharge power of 1350 W. Each propulsion system consists of a thruster and a Xenon Flow Controller Unit, pneumatic connections between which are realized by means of stainless steel pipelines. Propellant – xenon.
