About

The ST-40 Hall Thruster is engineered as a key component for propulsion systems in LEO-GEO satellites. Its design focuses on enabling mass manufacturing, positioning it as an economical choice for satellite constellations. A significant feature of the ST-40 is its multi-propellant capability, which allows it to be adapted for various satellite missions. This versatility extends to providing flexibility in both thrust and specific impulse, catering to diverse operational requirements in space. The thruster is part of a broader family of electric propulsion systems, including the SPS-100, SPS-40, SPS-25, ST-100, and ST-25, as well as power processing units like the PPU-500 and PPU-200, and the XFS mass flow controller, all designed for space applications.
