Real-time multipath detection and mitigation

A multipath error detection system (100) includes a first antenna (105) configured to receive a right hand circular polarized signal from a satellite (115) and a second antenna (110) configured to receive a left hand circular polarized signal from the satellite (115). At least one processor (130) is...

Beschreibung
Zusammenfassung:	A multipath error detection system (100) includes a first antenna (105) configured to receive a right hand circular polarized signal from a satellite (115) and a second antenna (110) configured to receive a left hand circular polarized signal from the satellite (115). At least one processor (130) is in signal communication with the first and second antennas (105, 110), and is programmed to determine, from the right hand circular polarized signal and left hand circular polarized signal, respective first and second values of a first parameter and respective third and fourth values of a second parameter. The at least one processor (130) is further configured to determine, based on the values, the presence of a multipath error associated with at least one of the polarized signals.
