摘要
描述航天器接近伴飞过程及其相对运动关系,分析相对轨迹预报的必要性和传统预报方法的不足,建立相对轨迹预报模型,并从模型误差和测量误差两方面对预报精度进行了分析;最后探讨了误差传播特点和规律。
This paper described the formation flying process of two space vehicles and their relative movement, analyzed necessity of relative trajectory forecasting and deficiency of traditional methods, established the model of relative trajectory forecasting, and evaluated the forecasting precision according to the error of model and that of measurement. Finally, error propagation rules and characteristics are discussed.
