摘　　要：为在倾角偏置条件下保持太阳同步轨道卫星的地面轨迹,在考虑地球扁率摄动、大气阻力摄动和太阳引力谐振等主要影响因素,以及卫星地面轨迹允许漂移范围的基础上,采用主动超调与被动控制结合的策略,提出了一种初始半长轴偏置后的卫星地面轨迹保持方法。分析了半长轴和倾角摄动变化率,以及初始半长轴和倾角偏置量对地面轨迹漂移的影响。仿真结果表明,该法可基本满足设计阶段的精度要求。For keeping the ground-track of sun-synchronous orbit satellite with initial inclination biased, a groundtrack keeping method using the combination of active overshooting and passive control was put forward based on the consideration of the compression perturbation, atmosphere drag perturbation and solar gravitation, and allowed drift range of satellite＇s ground-track in this paper. The effect of rate of change for semimajor axis and inclination perturbation and drift of semimajor axis and inclination on the ground-track drift was analyzed. The simulation results showed that this method could meet the requirement in initial design.
