Propulsion Electrique

PAPE PAPE - Propulsion Electrique

The Electric Propulsion is at a crossroad of its history. Indeed, it is now widely used on commercial satellites for North-South Station Keeping (NSSK)  maneuvers. But the significant mass savings, associated with recent in-flight achievement, allow perspectives which were not possible before. Thus, the electric propulsion technology  is not only foreseen for operations of station keeping but also for orbit raising of geostationary/navigation satellites, which opens a considerable market.

Moreover, Nano-satellites are new comers for space applications which can benefit from electric propulsion systems. Besides, guiding and controlling very small satellite trajectories as well as their orbital drift requires compact and robust electric propulsive systems. This is why new innovative and efficient propulsion systems are needed, and new paths have to be explored.

This turning point means a deep thinking about this new game changing brought by electric propulsion:

pe

  • in the short term, propulsion subsystems shall be suited to these new applications and shall increase their competitiveness (GEO, telecom),
  • in the middle term, the new product line will have to meet the needs of futures missions (LEO, constellations, nanosat),
  • in the long term, breakthrough has to be performed for more ambitious missions (space-Tug, far-off explorations, …).
