- Abstract:
- In order to improve the performance of multipath mitigation in tracking Galileo signals, a new multipath mitigation method named early-late strobe correlator(ELSC)is proposed.By applying the strobe correlator used widely in global positioning system(GPS)scenarios to Galileo E1 signals, it can be found that the strobe correlator has an undesirable level of performance when the delay of multipath signals is about 0.5 chip.Combining several strobe correlators, the ELSC can effectively mitigate the multipath effect especially for the multipath signals with the 0.5 chip delay.The multipath error envelopes between the strobe correlator and the ELSC are compared for Galileo E1 signals.The simulation results indicate that the ELSC performs excellently on multipath mitigation, and can be applied in both Galileo scenarios and GPS scenarios.
