摘　　要：通过设计航天器轨道,可使航天器发射入轨后无需机动即实现对Walker星座中非共轨的多颗卫星的快速、近距离接近。给出了该轨道的搜索方法以及基于星座特性的代换法,并给出了仿真示例。A spacecraft that have been launched into orbit can fast close approach multiple non- coplane satellites of Walker Constellation without orbital maneuver by orbital design, since Walker Constellation has several special characteristics in construction, such as symmetry. To approach without orbital maneuver, the height of the spacecraft must be as same as that of the Constellation. Aimed at Walker Constellation, this paper presents a search method and a substitution method that on the base of the characteristic of Constellation. For a given Walker Constellation, both method can get a series of orbits with different orbit inclination. Typical orbits derived from the two methods are given. Each orbit can fast （in half of orbit period） close approach （zero distance for Walker） multiple （2 or more） non-coplane satellites of Walker Constellation.
