Modern day infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). Given their low received signal power levels, GNSS signals are vulnerable to unintentional and intentional Radio Frequency Interference (RFI), which degrade the performance of systems that depend on GNSS, and in extreme cases systems become unavailable. With the growth in popularity of (illegal) personal privacy devices, which jam GNSS, the potential for serious consequences is increasing.

This one day workshop, organised by the Australian Centre for Space Engineering Research (ACSER) at the University of New South Wales (UNSW) and sponsored by the IET Radar, Sonar and Navigation Network and ACSER, to be held at the UNSW, Sydney, on 4 December 2013, will bring together speakers from government organisations, companies and universities working in the field and day-to-day GNSS users. Discussions will cover the reliance of critical infrastructure on GNSS, the extent of potential damage and vulnerability, and possible solutions to alleviate these vulnerabilities.
