The faults happened frequently when the target spacecraft is on-orbit. To solve this problem, the positioning technology of the target spacecraft’s on-orbit fault based in fault tree analytical technique is on research. The basic concept and analytical principle of fault tree are introduced, and the building process of the on-orbit fault tree is presented. The method is verified by an example of the power supply system fault of a certain type satellite. The result show that the method is feasible and the following process of on-orbit fault detection could be implemented.
