GPS vulnerabilities and the benefits of eLoran

The General Lighthouse Authorities of the UK and Ireland (GLAs) fully support the findings of the Royal Academy of Engineering’s paper on the dangers of heavy dependency on GPS, discussed on 10th March by Professor Martyn Thomas at the 2011 GNSS Interference, Detection and Monitoring Conference.

Over the last few years, the GLAs have conducted two GPS jamming trials to investigate and demonstrate the effects of GPS failure on the maritime industry, which has an enormous reliance on GPS for positioning, navigation and timing information.
