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.
