摘要
交会对接是空间站工程中一项非常重要的技术.对于给定的交会对接任务,设计可行的变轨策略,找出简单的计算变轨参数的算法是十分必要的.将高斯变分方程在参考轨道附近线性化得到一组线性化的轨道根数偏差方程,将该偏差方程的解作为二体模型解的初值进行轨道根数打靶,然后将所得到的二体模型的解作为摄动模型解的初始进行打靶.结果表明该迭代算法能很快收敛到摄动模型下的交会对接解.
Rendezvous and docking is a key issue for space station construction. In order to perform the rendezvous and docking mission,it is necessary to design a feasible maneuvering strategy and a corresponding algorithm and to obtain the maneuvering parameters. A fast shooting method based on Gaussian variational equation of orbit elements is investigated in this paper. The variational equation is linearized along the reference orbit,and its solution is substituted into two-body equation as its initial condition. And then the solution obtained from the two-body equation is substituted again into full model with perturbations as its initial condition. Simulation results show that this iterative algorithm can obtain for full model by only few steps.
