UK 'relying too heavily' on sat-navs

The UK is "dangerously dependent" on GPS satellite navigation systems, a report by engineers warns.

Back-up systems are often inadequate, while equipment which can illegally jam systems is easily available, the report from the Royal Academy of Engineering added. With Global Navigation Space Systems affecting road, rail and shipping equipment, a system failure could "conceivably cause loss of life", said Dr Martyn Thomas, chair of the academy's GNSS working group.
