WebSep 17, 2010 · GPS multipath is caused by the reception of signals arrived not only directly from satellites, but also reflected or diffracted from the local objects. Multipath results in an error in pseudorange measurements and thus affects the positioning accuracy, since the multipath signal takes a longer path than the direct signal. WebApr 1, 2008 · 3. Multipath Estimation Methodology [8] In order to correct for multipath on the GPS carrier phase, amplitudes A m and A d and multipath relative phase ψ must be estimated as a function of time. The …
