GNSS C/N0 Degradation Model in Presence of Continuous Wave and Pulsed Interference

Abstract : In the context of GNSS L5/E5a interference environment dominated by DME/TACAN and JTIDS/MIDS pulses, RTCA DO-292 [1]proposes to implement a temporal blanker mechanism to mitigate the detrimental impact of the pulsed interference signals on the nominal functioning of a generic GNSS receiver. Moreover, RTCA DO-292 also proposes a model to compute the received useful signal degradation due to the interference signals by increasing the noise power spectrum density (PSD), called the effective , where the increase is expressed as a function of the blanker duty cycle and the equivalent noise level contribution of the non-blanked interference
