Gizmag -- Researchers have found a better way to crunch the data that GPS-enabled devices use to determine their location. The result could provide a level of accuracy down to the centimeter that's needed in things like autonomous vehicles and other precision tech.

We've seen other efforts to improve GPS location to centimeter-level accuracy using what's called "differential GPS," that makes use of ground-based reference points in addition to satellite GPS data. This latest effort from the University of California - Riverside (UCR) seems similar in that it's basically a software-based approach.

What's perhaps most revolutionary about the advance is not just the improved level of accuracy, but just how efficiently centimeter-accurate positioning is established.

"Achieving this level of accuracy with computational loads that are suitable for real-time applications on low-power processors will not only advance the capabilities of highly specialized navigation systems – like those used in driverless cars and precision agriculture – but it will also improve location services accessed through mobile phones and other personal devices, without increasing their cost," said UCR professor Jay Farrell, who led the research.
