One of the electric propulsion technologies under development is the Quad Confinement Thruster (QCT), which is a high performance plasma propulsion system for spacecraft. The unique feature of this design is that the thrust produced by the device can be actively vectored by a unique configuration of electromagnets. QCTs have potential applications for large geostationary satellites because of potential cost savings due to the elimination of thruster gimbaling systems and are attractive because of their relatively high thrust performance at low levels of power.
