New Technique Makes GPS Accurate Down To The Centimeter

This should prove useful for particular applications, such as autonomous vehicles.

Achieving centimeter accuracy requires "GPS carrier phase integer ambiguity resolution." Until now, combining GPS and IMU data to solve for the integers has been computationally expensive, limiting its use in real-world applications. The UCR team has changed that, developing a new approach that results in highly accurate positioning information with several orders of magnitude fewer computations.
