Abstract :
This paper describes the progress of an advanced pulsed plasma thruster (PPT).The PPT currently being developed for flight which represents a significant leap in technology compared to previous flight models. The PPT will be used to extend satellite life from about 1-3 months to over one year by raising it´s operational orbit. The PPT is an ideal propulsion system for extending the small satellite life because of it´s high specific impulse (>;1000 sec), low system wet mass (<;5 kg), and inert nature when not powered (thus minimizing shuttle integration issues). In addition to the life enhancement mission, the on-orbit operations have been specifically designed to rigorously test the PPT ant to demonstrate it´s compatibility with the satellites spacecraft in order to validate it for commercial satellites.
