Abstract

Multipath is one of the main error sources when tracking signals in the GNSS systems. The presence of reflected signals gives place to a bias when estimating the propagation delay of the direct signal. There are several ways for mitigating this multipath problem. Several solutions have already been discussed for different techniques such as Narrow Correlator, Double delta or Early1/Early2 where the key factor concerns the discriminator curve shape to be used in a conventional DLL(delay lock loop).
