Innovation: Correlator beamforming for low-cost multipath mitigation Posted on 13 Jan 2017 in the Featured Stories & From the Magazine & Innovation categories.

GNSS Pest Control
A new solution for GNSS multipath employs a multi-element antenna with RF signal switching and a single front end to reduce complexity, power consumption and cost. Correlator beamforming, initially used in the 2.4 GHz frequency band where it has proven effective at mitigating multipath in heavy industrial environments, has been successfully adapted for GNSS use.
