Researchers at the University of California, Riverside have developed a new, more computationally efficient way to process data from the Global Positioning System (GPS), to enhance location accuracy from the meter-level down to a few centimeters.

The optimization will be used in the development of autonomous vehicles, improved aviation and naval navigation systems, and precision technologies. It will also enable users to access centimeter-level accuracy location data through their mobile phones and wearable technologies, without increasing the demand for processing power.

The research, led by Jay Farrell, professor and chair of electrical and computer engineering in UCR”s Bourns College of Engineering, was published recently in IEEE”s Transactions on Control Systems Technology. The approach involves reformulating a series of equations that are used to determine a GPS receiver”s position, resulting in reduced computational effort being required to attain centimeter accuracy.
