The characterization of the error budget related to GNSS can be performed over each component that affects the SIS measurement (pseudorange). Politecnico di Torino Fabio Dovis - Paolo Mulassano NAVSAS Group Considering the Galileo case, there are several error sources due to the receiver design; among them, the major one is the deleterious superimposition of the same SIS received at the antenna via multiple path: the multipath. Such an error is the most important contribution if indoor navigation/positioning is considered, and in addition it is also present in differential-GNSS applications where the reference station is located in a different environment with respect to users. This work presents an overview of possible multipath mitigation techniques applied to Galileo SI
