基于高斯分布的密度误差对航天器轨道的影响分析

Analysis of Effect of Gauss Distribution Density Error on Spacecraft Orbit

在航天器轨道预报的气动力计算中,加入不同高斯分布参数的热层模式密度相对误差,给出相应情况下的轨道预报误差。解答热层模式密度的均值标准差特性如何影响轨道预报的问题,为热层模式改进、建模指明方向。

In the aerodynamic calculation of spacecraft orbital prediction, the relative errors of the thermosphere model density with different Gauss distribution parameters are added to give the corresponding orbital prediction errors. The problem of how the mean standard deviation characteristics of the thermosphere model density affect the orbit prediction can be solved, and the direction for the improvement and modeling of the thermosphere model is pointed out.
