Abstract: Basedonastatetransitionmatrix,amethodforspacecraftmultiplepulsehoveringwaspresented.Therelativemotiondynamicsmodelandthestatetransitionmatrixwereintroducedtodescribetherelativemotionoftwospacecraftincircular,ellipticalandhyperbolicreferenceorbits.Amethodofachievingtheorbittransfervelocityincrementforhoveringwasdeducedusingthestatetransitionmatrix.Thenumericalsimulationshowsthattheproposedmethodcanachievespacecraftrelativehoveringeffectively.Withtheincreasingofimpulsenumber,theprecisionofrelativehoveringispromoted.Moreover,theprecisionofrelativehoveringisinfluencedbytheeccentricityofreferenceorbit.
