ST-40 Hall Thruster

The ST-40 Hall Thruster was designed for use as part of the propulsion system for Leo-Geo satellites, and the new ways of mass manufacturing make it a perfect low-cost solution for constellations of small satellites. With the ST-40 thruster, the small private operators or satellites developers can utilize the same high-performance systems as government agencies with appropriate commercial-sized budgets. With multi-propellant capability, ST-40 can be used in various satellite missions with thrust and specific impulse flexibility.
