The invention discloses a spacecraft orbit determination method and device, a processor and electronic equipment. The method comprises the following steps: constructing a rotation matrix according to a target attitude quaternion corresponding to a target attitude of a target spacecraft; constructing a first partial derivative model of unloading acceleration in an inertial coordinate system to acceleration in a body coordinate system according to the rotation matrix, and selecting a second partial derivative model in a target direction from the first partial derivative model according to target control characteristics; according to the second partial derivative model and observation data of the target spacecraft, constructing a state equation of the target spacecraft, and performing integral solution to obtain a target acceleration; and determining the orbit of the target spacecraft according to the target acceleration. According to the method and the device, the problem that the orbit determination error is relatively large due to the fact that the unloading acceleration is solved unstably because the acceleration generated by unloading the momentum wheel of the spacecraft is mainly calculated by adopting a uniform acceleration model under an orbit coordinate system or a celestial reference system in the prior art is solved.
