I went for a ride along with a couple geologist to a site near one of San Diego's local fault lines. The purpose of the trip was to extract data from a GPS receiver/data recorder. They told me the device could track movements of a few centimeters, and they used it to monitor shifts in the fault.
I did a little searching for GPS devices, the best accuracy I could find was .5 meters. So how do you suppose they were able to get this kind of accuracy. Are there GPS chips with this sort of accuracy? Any links?
