In this paper a Nonlinear Variable Dimension Estimator is proposed for tracking maneuvering spacecraft. Two process models were incorporated by the Unscented Kalman Filter to account for the dynamic uncertainties of the target of interest: a nonmaneuvering model based on the two body problem and a maneuvering model taking the forced acceleration as the unknown system input to be estimated.

当飞行器处于无机动的巡航状态时，无色卡尔曼滤波器使用常规的二体问题模型描述其运动规律，而当飞行器被认为开始机动后，滤波器将扩展系统的状态空间，将机动加速度作为状态变量进行估计，从而增加了模型的适应性。
