Space debris attitude perturbation calculation method

The invention discloses a space debris attitude perturbation calculation method, which comprises the following steps of: calculating aerodynamic force and moment suffered by space debris, and further calculating debris attitude precession angular velocity under the action of aerodynamic moment; calculating the gravity gradient torque borne by the space debris, and further calculating the debris attitude precession angular velocity under the action of the gravity gradient torque; calculating the geomagnetic moment borne by the space debris, and further calculating the debris attitude precession angular velocity under the action of the geomagnetic moment; the sunlight pressure moment borne by the space debris is calculated, and then the debris attitude precession angular velocity and the debris attitude nutation angular velocity under the action of the sunlight pressure moment are calculated; and adding the obtained debris attitude precession angular velocity and nutation angular velocity, and integrating to ob
