GPS system could transform virtual reality
Scientists have built a low-cost centimeter-accurate GPS system that reduces location errors from the size of a large car to the size of a nickel — a more than 100 times increase in accuracy. The breakthrough is a powerful and sensitive software-defined GPS receiver that can extract centimeter accuracies from the inexpensive antennas found in mobile devices.
