Abstract在圆/近圆参考轨道下,依据含有J_2摄动的卫星相对运动动力学模型,提出将变化幅度较小的地心距及轨道倾角平均化,求解J_2摄动下卫星相对运动动力学模型,获得了适用于任意初始条件的、以相对位置和相对速度为变量的、解析形式的J_2摄动卫星相对运动方程。仿真结果表明,与经典CW方程相比,J_2摄动下卫星相对运动精度提升明显,证明了所提方法的合理性和准确性。
Other AbstractSatellite's orbital elements can contain secular and periodic components under the J_2 perturbation which results in that the relative motion dynamics model become transcendental equations and the analytical solutions can not be obtained through conventional methods. Under this circumstances,the distance can be averaged among the satellite,the earth center and the orbit inclination so that the relative motion dynamics model can be solved and the analytical relative motion equations can be obtained under J_2 perturbation force when the reference orbit is circular or elliptical with very small eccentricity. Simulations results show that the precision of relative motion can be improved greatly by comparing with CW equations. It demonstrates the effectiveness and veracity of the new method.
