The past few years have allowed ALCATEL SPACE to design, develop and qualify complete chemical bi-propellant and electric propulsion systems for use on commercial telecommunication satellites ordered by major satellite operators [1]. Taking into consideration the continuous increase of satellite international competition with respect to price, performances, and adaptation to customer constraints, it was decided to improve the Bi-Propellant Chemical Propulsion System, on the basis of the generic Spacebus 4000 UPS. The improvements are mainly focussed on: -Apogee Boost Motor performance increase for spacecraft mass saving / lifetime increase -Qualification of Attitude Control Thrusters with new thruster valve, for better market flexibility -Pressure Regulation Module and Propellant Regulation Module qualified at system level with use of new components from European suppliers, for better market flexibility linked to exportation contraints. The aim of this paper is to describe the development and qualification status of this improved Propulsion System.
