摘　　要：中星18号卫星自发射后一直处在大椭圆转移轨道上,工作异常,且携带满仓燃料,具有一定危险性。本文以该星为研究对象,从影响大椭圆轨道的动力学出发,对该星进行了轨道寿命仿真和分析,然后分析了近一年关于该星的公开编目情况和我国编目结果,理论、仿真和实测结果相互验证,结果表明短期内中星18号卫星不会陨落,仍需保持长期跟踪监测。ChinaSat-18 has been in a highly elliptical orbit since its launching.It is very dangerous because of its abnormal state with full fuel.In the paper,the dynamics of the highly elliptical orbit influenced by the lunar-solar perturbations is studied,then the orbital life is analyzed using the semi-analytical orbital prediction software.Finally,the public catalog,the observation and catalog from Purple Mountain Observatory for ChinaSat-18 are presented and analyzed.It is demonstrated that the observation results agree with the theoretical and simulation results.ChinaSat-18 will be in orbit for a long time and needs to be observed constantly.
