摘要：

GNSS L5/E5a interference environment is dominated by DME/TACAN and JTIDS/MIDS pulses causing a degradation of the effective C/N0 observed by the receiver. A time-domain blanker is implemented to mitigate their impact. RTCA DO-292 proposes a model to compute the C/N0 degradation of the received useful signal by the increase of the noise PSD. This paper focuses on the impact of DME/TACAN RFI signals. Simulated results as well as predicted results are presented for US and Europe scenarios. The predicted results are calculated from an updated C/N0 degradation formula with respect to RTCA DO-292 proposed formula. The impact of GNSS receiver RFFE filter bandwidth and blanker threshold are evaluated.
