What does PS stand for?

The company was later selected to provide the propulsion subsystem - a bi-propellant system which uses an oxidizer and fuel to propel the satellite after separation from the launcher to its final orbital position.

The determination of identifying thrusters with propulsion or reaction control depends on their main purpose; if the satellite is already in a proper orbit, no propulsion subsystem is needed, and the thrusters (RCS) are identified with the ACS, whose functions are vital to spacecraft operation--both bus and payload.

Anglo-French Matra Marconi was the main contractor in a [pounds sterling]34million project for key propulsion subsystems for the 10ft diameter satellites.

This is a subcontract to BAE Systems, the Power and Propulsion Subsystem integrator to Lockheed Martin Missiles and Fire Control, the prime contractor for the MULE vehicle, who was recently awarded the System Development and Demonstration (SDD) Phase.
