论文摘要
我们讨论了使用专用的采集传感器在空间中获取光链路的各种方法。统计模型是开发的，并得出了简单的分析方程，该方程比较了单个螺旋扫描方法和链路链的顺序和并行习得之间的性能。简单的派生分析方程允许将基本搜索参数（例如轨道宽度，不确定性分布的方差，捕获半径和扫描速度的差异）与在特定时间内获取链接的概率相关联。我们还评估了由于横梁抖动而无法获得链接的概率，并得出了一个简单的分析模型，该模型允许确定给定光束重叠的最大可容忍抖动和成功的可能性。所有结果均由蒙特卡洛模拟验证，并应用于Grace FO任务的具体示例。
We discuss various methods for acquiring optical links in space using a dedicated acquisition sensor. Statistical models are developed and simple analytical equations derived that compare the performance between a single and dual spiral scan approach as well as between sequential and parallel acquisition of link chains. Simple derived analytical equations allow relating essential search parameters such as track width, variance of the uncertainty distribution, capture radius and scan speed to the probabilities of acquiring the links within a specific time. We also assess the probability of failing to acquire a link due to beam jitter and derive a simple analytical model that allows determining the maximum tolerable jitter for a given beam overlap and required probability of success. All results are validated by Monte Carlo simulations and applied to the concrete example of the GRACE FO mission.
