RedEaredSlider writes "A new report from the Royal Academy of Engineering in London suggests developed nations have become too reliant on GPS systems. The report from the Academy focuses on global navigation satellite systems (GNSS) and their vulnerabilities. These vulnerabilities include deliberate or accidental interference, both man-made (such as jamming) and natural (such as solar flares). While most people equate GPS systems with the tiny screens which get drivers from point A to point B, the report says society's reliance on the technology goes well beyond that. The Academy says the range of applications using the technology is so vast that without adequate independent backup, signal failure or interference could potentially affect safety systems and other critical parts of the economy."
