Abstract: To make preparations for the rendezvous and docking, the target phasing maneuver mission is a non-fixed time rendezvous problem. According to the basic phasing principle, the phase influences by atmosphere drag, drift of right ascension of ascending node and orbital errors were analyzed and used to improve the approximate formulae, which estimated the effect of impulse on the phase angle. With the combination of the approximate formulae and the numerical integration, the target phasing strategy was improved in three aspects: the calculation of maneuver data for the perturbed trajectory, the selection of the phasing-direction and the selection of the maneuver revolution number. The simulation results show that the proposed target phasing strategy can obtain the maneuver data for the perturbed trajectory and can meet the terminal precision requirements. Compared with the phasing-direction selection method, with which only the terminal phase angle deviation is considered, the proposed strategy can reduce the fuel consumption.
