SPS-40 Propulsion System

The SPS-40 Propulsion System leverages the leading-edge Hall thrusters and is optimized for small mass class satellites. The main objectives are to adjust the positions of satellites and deorbit after the finish of their operational lifespan. Designed with state-of-the-art Hall thruster technology based on permanent magnets delivering superior performance, and is a significant step forward to miniaturize thrusters without reliability compromise.
