Abstract:	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 computation on the max value of the I_GNSS term.
