PPS-1350 is a Hall-effect thruster, a kind of ion propulsion system for spacecraft. It was used in the SMART-1 mission to the moon and two geostationary satellites: Inmarsat-4A F4 and Hispasat AG1.

|Specific impulse||1660 s|
|Total impulse||3.4×106 N-s|
It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field. The PPS-1350 is built by Snecma, a French aerospace firm, in cooperation with Fakel, who designed the SPT-100, on which the PPS 1350 is based.
