In an article in the current edition of GPS  World, AFIT's Dr. Sanjeev Gunawardena, a Research Assistant Professor within the Electrical and Computer Engineering Department, asks "Which is more important for GNSS equipment: the antenna or the receiver?"  The article covers  a new solution for GNSS multipath employing 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.
