Method of and receiver for mitigating multipath interference in a global navigation satellite system
Patent number: 11585944Abstract: A method of and a receiver for mitigating multipath interference in a global navigation satellite system. In accordance with an embodiment, GNSS signals are received from a plurality of satellites in at least two frequency bands. A likelihood indicator is determined which is indicative of how likely the received GNSS signals are affected by multipath interference. In response to the likelihood indicator, all GNSS signals from at least one frequency band of the at least two frequency bands are discounted. The received GNSS signals are processed by taking into account said discounting of all GNSS signals in the at least one frequency band. The discounting may include assigning less weight to the discounted frequency bands or disregarding each of the discounted frequency bands in their entirety.Type: GrantFiled: November 5, 2020Date of Patent: February 21, 2023Assignee: u-blox AGInventors: Paula Syrjärinne, Christoph J.
