摘要
GEO轨道是重要的轨道资源,针对现有光学探测手段对地球同步轨道的覆盖性问题,基于地球遮挡约束,地影约束,太阳光干扰约束、观测视场角约束、相对角速度约束建立了空间目标可见性模型。采用串行算法对模型进行求解和仿真。仿真给出了目标的可见时长及GEO轨道带的瞬时覆盖率。结果表明,现有的监视系统对地球静止轨道瞬时覆盖率同季节相关且整体覆盖率较低。
GEO belt is the important orbit resource.Focus on the coverage problem of geosynchronous orbit by existing optical detection methods,the visibility model of space surveillance was established based on the earth shelter constraint,earth shadow constraint,solar interference constraint,field of view constraint and relative angular velocity constraint in space optical observation.The model was solved using a serial algorithm.The simulation gives the visible time of target and the instantaneous coverage rate of GEO belt.Results show that the surveillance system has a seasonal coverage of the GEO orbit and the average coverage rate is low.
