Thales Alenia Space Experience on Plasma Propulsion
Thales Alenia Space Experience on Plasma Propulsion IEPC-2007-301 Presented at the 30th International Electric Propulsion Conference, Florence, Italy September 17-20, 2007 Michel LYSZYK* and Laurent LECARDONNEL.† Thales Alenia Space, Cannes, 06150, France Abstract: Thales Alenia Space experience on plasma propulsion has been developed in the frame of Stentor, Astra 1K and GEI programs with plasma propulsion systems using SPT100 thrusters manufactured by Fakel and commercialized by Snecma . The PPS (plasma propulsion system) use in house equipments such as Power Processing Unit (PPU) manufactured by TAS-ETCA in Charleroi and the Thruster Orientation Mechanism (TOM) manufactured by TAS-France in Cannes . The PPS subsystem is used on board our SpaceBus satellite family to perform North-South station keeping. The on going activity on the XPS (Xenon Propulsion System) is devoted to the next European platform Alphabus currently under joint development by Thales Alenia Space and Astrium with CNES and ESA support. The XPS uses also the PPU manufactured by TAS-ETCA , the TOM manufactured by TAS-France and the Xe tank developed by TAS-Italy ; it use also the PPS1350 thruster under qualification by Snecma , a xenon regulator and a latch valve under development at Marotta Ireland. I. Introduction HIS document describes the Thales Alenia Space experience gained through Stentor , Astra 1K , GEI, T Spacebus and Alphabus programs on plasma Hall effect thrusters propulsion subsystems . For Spacebus application a description of the subsystem is given together with the general achieved performances . For Alphabus application a general status of the on going activities is given . * Head of electric propulsion section, Propulsion Department, [email protected]. -

Power Processing Unit Activities at Thales Alenia Space Belgium (ETCA)
Power Processing Unit Activities at Thales Alenia Space Belgium (ETCA) IEPC-2013-213 Presented at the 33rd International Electric Propulsion Conference, The George Washington University • Washington, D.C. • USA October 6 – 10, 2013 Eric Bourguignon1, Stéphane Fraselle2 and Thierry Scalais3 Thales Alenia Space Belgium (ETCA), B-6032 Charleroi, Belgium Abstract: Since 1996, Thales Alenia Space Belgium (ETCA) designs, develops and produces Power Processing Unit (PPU) to supply Hall Effect Thrusters: SPT-100 from Fakel and PPS1350-G from Snecma. The first qualification model, developed for the 50V bus Stentor program, has supplied during 8900 hours an SPT-100 thruster in a vacuum chamber simulating space environment. Qualified for the SpaceBus 4000 platform, with a 100V regulated bus, the SB4000 PPU and Filter Unit EQM have cumulated 6300 hours ground operation with a PPS1350-G thruster. Twenty three PPU flight models were delivered for the Stentor, Astra-1K, Smart-1, Intelsat, Inmarsat, Eutelsat, Yahsat satellites. In October 2005, the Smart-1 spacecraft reached the Moon after 4958 hours of cumulated operation of the PPU and its PPS1350-G thruster. Fourteen PPU’s currently in flight for North South Station Keeping on seven telecom satellites have cumulated more than 20900 hours flight operation. Following the selection of the PPS1350-G as baseline thruster for the AlphaBus platform, the AlphaBus PPU was developed and two flight models were delivered for AlphaSat, launched in July 2013. The flight validation of the AlphaBus electrical propulsion has been performed successfully in August 2013. On the SmallGEO platform, one EPTA branch has to drive one out of four SPT-100 thrusters. -

The Industry Defined the Space Industry Is Segmented Into Three Distinct Areas: Space, Control, and User
Spring 2007 Industry Study Final Report The Space Industry The Industrial College of the Armed Forces National Defense University Fort McNair, Washington, D.C. 20319-5062 SPACE INDUSTRY STUDY 2007 ABSTRACT: U.S. space domination is far from guaranteed as the number of space-faring nations increases. The U.S. space industry remains a critical element in providing capabilities essential to national security and economic prosperity. The ability to access space for communications, monitoring, research, and exploration is vital. To ensure these, U.S. policy should encourage more commercial activity in space, emphasize a more globally cooperative environment, change acquisition methods to emphasize cost control over performance at any cost, and focus government investments on technologies having the greatest impact on the space industry.
