PPS-1350

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 one geostationary satellites: Inmarsat-4A F4.^[1][2]

Manufacturer	Snecma
Hall-effect thruster
Performance
Thrust	90 mN
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.^[3] 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.^[4]
