Abstract :
Global navigation satellite systems (GNSS) are highly susceptible to interference, due to their low signal power. This paper studies the impact of DVB-T on the GPS L1 and Galileo E1 frequency band. An analytical tool has been developed to evaluate the probability of detection in the presence of interference, taking into account the possible effects of fading on the GNSS signal. Further, the tracking of GNSS signals has been simulated, estimating the degradation of the signal quality. Measurements on different receivers complete the study and illustrate the effects of DVB-T.
