SPS40 propulsion system

The SPS40 Propulsion System was designed for medium and large satellites and able to adjust the orbit parameters and insure the maneuverability of satellites in space. The propulsion system is designed for advanced satellites constellations in order to correct position relatively to each other.

SPS40 is based on two ST40 Hall Thrusters.
