为了帮助减轻全球导航卫星系统（GNSS）干扰机所造成的影响，本文演示了使用无人驾驶飞行器（UAV）能够自主定位的全球定位系统（GPS）干扰源的现场干扰演习主办的国土安全部（DHS）。在真实环境中开发用于干扰机定位的自主无人机需要解决三个主要挑战：干扰信号的精确测量、快速定位步骤和存在干扰时的可靠导航。我们的系统，干扰采集与GPS勘探和侦察（JAGER），已经开发出来，以解决这些主要挑战，快速定位，并已与本地化Wi-Fi信号之前进行了测试。本文概述了对JAGER的修改，以便能够从定位Wi-Fi源移动到定位GPS干扰机。修改包括新的传感设备，用于确定方位的干扰机和额外的导航系统飞行，而干扰机是活跃的。测试的主要目标是证明JAGER在实际距离定位GPS干扰机的可行性以及几种不同定位方法的性能。第二个目标是探索可能的GPS拒绝导航解决方案。
To assist in the mitigation of the effects posed by Global Navigation Satellite System (GNSS) jammers, this paper demonstrates the use of an unmanned aerial vehicle (UAV) capable of autonomously localizing the source of Global Positioning System (GPS) jamming in a live jamming exercise hosted by the Department of Homeland Security (DHS). Developing an autonomous UAV for jammer localization in a real-world environment needs to address three main challenges: accurate measurements of the jamming signal, rapid localization steps and reliable navigation in the presence of interference. Our system, Jammer Acquisition with GPS Exploration and Reconnaissance (JAGER), has been developed to address those main challenges for rapid localization and has been previously tested with localizing Wi-Fi signals. This paper outlines the modifications to JAGER required to be able to move from localizing Wi-Fi sources to localizing GPS jammers. Modifications include new sensing equipment for determining the bearing to the jammer and additional navigation systems to fly while the jammer is active. The main goal for the testing was to demonstrate the feasibility of JAGER to localize a GPS jammer at realistic distances and the performance of several different localization methods. The second goal was to explore possible GPS-denied navigation solutions.
