Abstract

One of the major use cases of GNSS signals is precise time keeping but introduction of interference signals has threatened the reliability of such a functionality. Therefore, it is necessary to identify signal types most threatening to GNSS and adopt solutions as they evolve. We studied the performance of a timing-grade GNSS receiver in presence of interference signals. We tested the robustness of the receiver against different classes of signals which were captured in real world and identified as most threatening interference to GNSS by the EU Horizon 2020 research project STRIKE3. We showed that the quality of the time solution provided by the receiver degrades in their presence. Through statistical analysis we characterized the degradation of the solution in case of different classes of interference signals.

针对现实世界干扰威胁的定时级GNSS接收机标准化测试的strike3案例研究
GNSS信号的主要用例之一是精确计时,但干扰信号的引入威胁了这种功能的可靠性。因此,有必要识别对GNSS威胁最大的信号类型,并随着它们的发展采取解决方案。研究了干扰信号存在下定时级GNSS接收机的性能。我们测试了接收器对不同类别信号的鲁棒性,这些信号是在现实世界中捕获的,并被欧盟地平线2020研究项目STRIKE3确定为对GNSS最具威胁性的干扰。我们发现,在它们存在的情况下,接收器提供的时间溶液的质量会下降。通过统计分析,表征了在不同干扰信号类别下解的退化。
