Hyundai Takes Vehicle Position Accuracy From Feet to Inches

Hyundai says it has designed a more accurate vehicle positioning system, boasting that it will take accuracy from multiple feet to fractions of an inch.
The Korean automaker claims High-Precision Positioning (HPP) will assist vehicle safety systems and emergency crews locate and treat injured passengers, help cities manage traffic flow, continue the advancement of self-driving technology, or communicate with other vehicles about its true position.
GPS, the standard for vehicle positioning, is used, but enhanced by the addition of cellular technology. GPS determines the initial location, then a correction of the position is applied by cellular. This is determined by a network of stationary receivers, sending the absolute position to the car’s central processing unit, which uses it as a permanent reference point.
As the stationary receivers are already in the cellular network, and the data transmission channels are already in place, Hyundai says HPP can be deployed quickly to its vehicles. The manufacturer is demonstrating the technology at CES 2020 in Las Vegas, using the 2020 Hyundai Sonata.
