ST-40 hall-effect thruster

The ST-40 Hall-Effect Thruster with an anode layer is designed for use as part of the propulsion system for satellites mass up to 1 T. It is used to orient and stabilize of the spacecraft in various orbits. The propulsion system provides a thrust of up to 28 mN at a maximum electric power consumption of 600 W. The propulsion system that contains ST-40 can be used on satellites for various purposes.
