Modern life now often depends on GPS (short for Global Positioning System), but it can err by several meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks that can deliver geolocation info accurate to within 10 centimeters in metropolitan areas.

The scientists detailed their findings 16 November in the journal Nature.

GPS and other global navigation satellite systems (GNSSs) such as China's Beidou are capable of reaching centimeter-level precision, notes study senior author Christian Tiberius, a navigation engineer at Delft University of Technology, in the Netherlands.
