Abstract: The capacity-constrained micro-spacecraft are carried by the space orbit platform before the rendezvous with a noncooperative target. In this article, an initial guidance law based on C-W equations and an end guidance law derived from the relative motion equation between the micro-spacecraft and the noncooperative target in line of the sight frame are designed. At the beginning of the rendezvous mission, the micro-spacecraft is released by the space orbit platform with certain velocity and release angle based on the initial guidance law to save fuel. Affected by the initial guidance, and after certain orbit periods, the sensor of micro-spacecraft captures the target, which provides some rendezvous conditions for the end guidance. The micro-spacecraft finally approaches the target by the end guidance law and fulfills the rendezvous mission.
