代数动力学算法首次被用于求人造地球卫星运动方程的数值解,在四阶算法下,与Runge-Kutta算法和辛算法的计算结果作了比较.结果表明,代数动力学算法对于人造地球卫星长期轨道的计算有较高的精度.并讨论了地球四极和八极带谐项对卫星轨道的影响.
The algebraic dynamics algorithm is firstly used to find the numerical solution of the artificial earth satellite motion equation, and compared with the Runge-Kutta algorithm and the symplectic algorithm under the fourth-order algorithm. The results show that the algebraic dynamics algorithm for the artificial Earth satellite The calculation of long-term orbits has higher accuracy and discusses the effect of the earth’s quadrupole and octupole band harmonics on satellite orbits.
