The invention discloses a satellite formation attitude cooperative control method based on axial angle cross coupling, and belongs to the technical field of satellite formation systems and cooperative control. The problem that the existing method cannot realize high-performance attitude cooperative control under the condition of different member satellite response speeds in the formation is solved. The method comprises the following steps of: 1, solving axial angle information of an attitude error based on a member satellite attitude tracking error quaternion, and transmitting the axial angle information to other member satellites; 2, calculating a cross-coupling collaborative error angle of the member satellite and a satellite communicating with the member satellite according to the axial angle information, performing amplitude limiting, calculating a tracking error angle correction amount through an adaptive function, performing correction and amplitude limiting on the tracking error angle of the member sat
