Academy report warns of over-reliance on global satellite navigation systems

Society may already be dangerously over-reliant on satellite radio navigation systems like GPS, the Royal Academy of Engineering warns in a report published today (8 March 2011). The range of applications using the technology is now so broad that, without adequate independent backup, signal failure or interference could potentially affect safety systems and other critical parts of the economy.

Global Navigation Space Systems: reliance and vulnerabilities looks into the increasing use of global navigation satellite systems (GNSS) to gain accurate data for positioning, navigation and timing (PNT). The US-operated Global Positioning System (GPS) is best known as the first major implementation of this technology but other GNSS systems are being planned and built, including the Russian GLONASS and Europe's Galileo.

The Academy's report focuses on our increasing reliance on GNSS and the current limited use of GNSS-independent backups for PNT data. The vulnerabilities of GNSS to deliberate or accidental interference, both man-made (such as jamming) and natural (such as solar flares) are also highlighted.....more
