The invention discloses a satellite cluster on-orbit reconstruction method based on a relative orbit element method, and the method comprises the steps: designing a satellite cluster target space configuration through a bifurcation dynamics method, and enabling the satellite cluster configuration to achieve the quick switching between a single circle and a double circle through the change of bifurcation parameters. A quadratic form satellite cluster control law is designed based on relative orbit elements and an artificial potential field method, and meanwhile, collision avoidance potential field control is introduced, so that a satellite group is converged to a target spatial configuration to realize rapid formation reconstruction; the method can be applied to on-orbit rapid reconstruction control of a large-scale satellite cluster, the on-satellite calculation amount is greatly reduced, meanwhile, the problem of an artificial potential field local minimum value is avoided, and the micro-satellite space natural relative motion rule under the condition that relative orbit elements meet the micro-thrust condition is utilized to achieve the on-orbit rapid reconstruction control of the large-scale satellite cluster. And rapid switching of spatial configurations such as circular ring-spherical surface-ellipsoid of the satellite cluster can be realized through parameter change.
