GPS is such a common feature in mobile phones and gadgets nowadays that we’ve almost come to take the service for granted. We forget that there are 24 busy GPS satellites working to feed us all the location data that we’re requesting. There is some great news, though, as the United States is planning an $8 billion overhaul of the 24 aging satellites. With the new hardware, users will be able to get GPS data that’s accurate to about 3 feet, instead of the current level of accuracy (within 20 feet). Do you already own a device that supports GPS capabilities, or are you in the midst of planning to buy one?
