A ne. non-simplifie. mode. of formation flying is de.ive. in the.pre.e.ce.of an oblate.main- body and third-body pe.turbation. In the.propose. mode., conside.ing the.pe.turbation of the.third- body in an incline. orbit, the.e.fe.t of obliquity （axial tilt） of the.main-body is be.oming important and has be.n propounde. in the.absolute.motion of a re.e.e.ce.sate.lite.and the.re.ative.motion of a followe. sate.lite. From a ne. point of vie., J2 pe.turbe. re.ative.motion e.uations and conside.ing a disturbing body in an e.liptic incline. thre. dime.sional orbit, are.de.ive. using Lagrangian me.hanics base. on accurate.introduce. pe.turbe. re.e.e.ce.sate.lite.motion. To validate.the.accuracy of the.mode. pre.e.te. in this study, an auxiliary mode. was constructe. as the.Main-body Ce.te. base. Re.ative.Motion （MCRM） mode.. Finally, the.importance.of the.main-body＇s obliquity is de.onstrate. by se.e.al e.ample. re.ate. to the.e.rth-Moon syste. in re.ative.motion and lunar sate.lite.formation ke.ping.
