A study of multipath effects on Galileo signals

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 SIS
