At CES in Las Vegas, Hyundai, Hexagon’s Positioning Intelligence Division, Valeo, and a major mobile network operator presented a new technology capable of pinpointing a vehicle’s exact location while it’s on the road.
Using proprietary cm-level precision called High-Precision Positioning (HPP), the system can further enhance a vehicle’s advanced active safety technologies. The use of GPS positioning is already widespread in the automotive industry, but the technology currently deployed in the automotive industry only approximates positioning to within 2-3 metres in optimum conditions.
HPP works by applying TerraStar X technology, a correction to the GPS signal received by the vehicle through a channel of the cellular network. The correction to be applied is determined by a network of stationary receivers, which knows their absolute position and serves as a permanent reference point.
