Presentation presentend on ION GNSS+ 2018 by Wim de Wilde and Jean-Marie Sleewaegen showing how a multi-antenna GNSS receiver with built-in RF spectrum monitor and adequate processing tool can efficiently detect and classify jamming events and identify offending cars or trucks on a highway to avoid paying toll. The five-day test was conducted with two Septentrio AsteRx-U dual-antenna receivers installed on an overhead structure above a busy highway.
