利用机会信号的自主系统相对定位

Relative Positioning of Autonomous Systems using Signals of Opportunity

Nicolas Souli, Panayiotis Kolios, Georgios Ellinas

摘要:

为了实现可靠的操作,下一代自主智能体将需要增强的态势感知和精确的导航能力。几乎所有现代定位系统所使用的全球导航卫星系统信号都不能满足提高自主水平的这一要求,定位正成为其扩散的决定性因素。这项工作研究如何使用环境中已经可以访问的信号来实现相对定位,并推导出一个在线程序,用于利用这些信号在GNSS挑战区域进行定位。建议的相对定位系统(RPS)探讨了信号特性的大频谱的频段,并推导出车辆跟踪算法,以准确地估计车辆的轨迹在空间和时间使用任意一组未知的参考位置。实验结果表明RPS的适用性,并研究其性能在不同的参数值。

英文摘要:

For reliable operation, next generation autonomous agents will need enhanced situational perception as well as precise navigation capabilities. The global navigation satellite system (GNSS) signals that are utilized by practically all modern positioning systems cannot satisfy this requirement for heighten autonomy levels and positioning is becoming a decisive factor for their proliferation. This work investigates how relative positioning can be achieved using signals that are already accessible in the environment, and derives an online procedure for the exploitation of these signals for localization in GNSS-challenged areas. The proposed relative positioning system (RPS) explores the signal properties over a large spectrum of frequency bands, and derives a vehicle tracking algorithm to accurately estimate the vehicle's trajectory in space and time using an arbitrary set of unknown reference positions. Experimental results demonstrate the applicability of RPS and investigate its performance over the different parameter values.
