N2 - This work presents a single-feed hemispiral antenna that leverages both hardware and software approaches to mitigate interference from jammers, spoofers, and unintended RF interference. The operation frequency range encompasses most known GNSS bands, but characterization specifically targets the L1, L2, and L5 bands for GPS. The diversity in the hemispiral's radiation pattern enables the receiver to perform DoA checks on incoming narrowband signals, distinguish between data from true satellites versus spoofers, and identify potential multipath signals. This added functionality can be implemented in parallel to a receiver's regular processing for satellite acquisition and tracking.
