摘要

The risk for current operational spacecraft or futurernmarket induced by large space debris, dead satellites orrnrocket bodies, in Low Earth Orbit has been identifiedrnseveral years ago. Many potential solutions andrnarchitectures are traded with a main objective ofrnreducing cost per debris. Based on cost consideration,rnspecially driven by launch cost, solutions constructed onrnmulti debris capture capacities seem to be muchrnaffordable The recent technologic evolutions in electricrnpropulsion and solar power generation can be used torncombine high potential vehicles for debris removal.rnThe present paper reports the first results of a studyrnfunded by CNES that addresses full electric solutionsrnfor large debris removal. Some analysis are currently inrnprogress as the study will end in August. It comparesrnthe efficiency of in-orbit Active Removal of typicalrndebris using electric propulsionrnThe electric engine performances used in thisrnanalysis are demonstrated through a 2012/2013 PPSrn5000 on-ground tests campaign. The traded missions arernbased on a launch in LEO, the possible vehiclernarchitectures with capture means or contact less, thernselection of deorbiting or reorbiting strategy.rnFor contact less strategy, the ion-beam shepherdrneffect towards the debris problematic will be addressed.rnVehicle architecture and performance of the overallrnsystem will be stated, showing the adequacy and thernlimits of each solution.
