太阳同步卫星降交点地方时漂移控制策略的研究

为将太阳同步卫星降交点地方时控制在允许的范围内,对其漂移因素进行分析,确定了卫星轨道设计和入轨偏差所导致的降交点地方时初始漂移速度,而大气阻力和太阳引力摄动则使得降交点地方时产生漂移加速度.针对产生漂移的原因,提出通过轨道偏置设计、轨道高度和轨道倾角保持控制等方法,将漂移限制在允许的范围内.仿真实验结果表明了所进行的分析和所提出的控制策略的正确性.

Study of shift control strategy for local time of descending node based on sun-synchronous satellite

To keep the local time shift of descending node for sun-synchronous satellites within an allowance range, the shift factors are analyzed. The satellite orbit design and the orbit injection deviation are the causes for the initial shift velocity, while the atmospheric resistance and the sun gravitational perturbation produce the shift acceleration. To deal with these shift factors, a shift control strategy is proposed, such as orbit bias design, orbit altitude and inclination keeping control. The simulation ...
