研究了自主交会中的纯角度相对导航问题。为了分析和提高相对位置和速度估计精度,提出了确定轨道机动的可观测度和潜在距离信息的方法。在光学相机是唯一可行的相对测量传感器的条件下,建立了纯角度相对导航方程,并利用牛顿迭代法得到了相对导航的DOO表达式。分析了轨道机动的潜在距离信息,并将其用于提高纯角度相对导航的DOO性能。仿真结果表明,DOO能有效地描述相对位置和速度的可观测性水平,潜在距离信息对提高纯角度相对导航的DOO性能有一定的作用。
This paper considers the problem of angles-only relative navigation for autonomous rendezvous. Methods for determining degree of observability (DOO) and latent range information of orbital maneuver are proposed for analyzing and enhancing the precision of relative position and velocity estimation. The equations of angles-only relative navigation are set forth on the condition that optical camera is the only viable sensor for relative measurement, and expressions for the DOO of relative navigation are obtained by using the Newton iterative method. The latent range information of orbital maneuver is analyzed, which is employed to enhance the DOO of angles-only relative navigation. Simulation result shows that DOO is effective to describe the observability level of relative position and velocity, and the latent range information is useful in enhancing the DOO of the angles-only relative navigation.
