Webdirect and multipath signals can be detected by a RHCP antenna, which will act to filter out most of the multipath signal, while allowing the direct signal to pass through. This improvement in the direct to multipath signal gain is the reason why GPS antennas are typically RHCP. Using polarization alone to discriminate against WebOct 23, 2024 · Multipath propagation is one of the main GNSS error sources, which constrains high-precision positioning.
