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. connections academy.orgWebMay 30, 2024 · Multipath occurs when the GPS satellite signal bounces off of nearby structures like buildings and mountains. In effect, your GPS receiver detects the same signal twice at different ranges. However, this error is a bit less concerning and could cause anywhere from 1 meter of position error.
