PPS®5000
Hall Effect Thruster
The PPS®5000, produced by Safran Spacecraft Propulsion, is a Hall Effect Thruster purposely designed for “all-electric” satellites. It can operate in high-thrust or high specific impulse mode,and offers an operating lifespan of about 20,000 hours. This means it can handle orbital positioning and station-keeping duties for a wide range of telecom and navigation satellites, as well as exploration spacecraft. The PPS®5000 was fully qualified in 2021.
PPS®5000 FEATURES
DESIGNED FOR ORBIT RAISING AND STATION-KEEPING
40% WEIGHT SAVING VERSUS CONVENTION PROPULSION
EXCELLENT THRUST-TO-ELECTRICAL POWER RATIO
VERY HIGH PERFORMANCE
The major advantage of the PPS®5000 is of course
its very high specific impulse, which allows significant
weight savings versus platforms using conventional
chemical propulsion. It also offers an excellent thrust –
to-electrical power ratio, which enables reducing
operating time or the number of thrusters needed.
It can be delivered as part of an electric propulsion
subsystem, including all thermal control functions.
UPCOMING MISSIONS
The PPS®5000 has been selected by Airbus Defence and Space and Thales Alenia Space for use on their Eurostar Neo and Spacebus Neo communications satellite platforms, respectively. It will handle both orbit raising and station-keeping duties. It has also been selected by Boeing company for use in a cluster of three PPS®5000 thrusters, operating simultaneously for orbit raising, at a power rating of 5 kW
