Nowadays, the Global Navigation Satellite Systems (GNSS) technology is not the primary means of navigation for civil aviation and Air Traffic Control, but its role is increasing. Consequently, the vulnerabilities of GNSSs to Radio Frequency Interference, including the dangerous intentional sources of interference (i.e., jamming and spoofing), raise concerns and special attention also in the aviation field. This panorama urges for figuring out effective solutions able to cope with GNSS interference and preserve safety of operations. In the frame of a Single European Sky Air traffic management Research (SESAR) Exploratory Research initiative, a novel, effective, and affordable concept of GNSS interference management for civil aviation has been developed. This new interference management concept is able to raise early warnings to the on-board navigation system about the detection of interfering signals and their classification, and then to estimate the Direction of Arrival (DoA) of the source of interference allowing the adoption of appropriate countermeasures against the individuated source. This paper describes the interference management concept and presents the on-field tests which allowed for assessing the reached level of performance and confirmed the applicability of this approach to the aviation applications.
如今，全球导航卫星系统（GNSS）技术并非民用航空和空中交通管制的主要导航手段，但其作用正在不断增强。因此，GNSS对射频干扰的脆弱性，包括危险的有意干扰源（即干扰和欺骗），也引起了航空领域的关注和特别重视。这种情况促使人们找出能够应对GNSS干扰并保障运行安全的有效解决方案。在单一欧洲天空空中交通管理研究（SESAR）探索性研究计划的框架内，已开发出一种新颖、有效且经济实惠的民用航空GNSS干扰管理概念。这种新的干扰管理概念能够向机载导航系统发出关于干扰信号检测及其分类的早期预警，然后估计干扰源的到达方向（DoA），从而能够针对识别出的干扰源采取适当的应对措施。本文描述了干扰管理概念，并介绍了现场测试情况，这些测试评估了所达到的性能水平，并证实了该方法在航空应用中的适用性。
