The GPS chip/unit embeded in cell phones is incredibly minimal (at least when I reviewed the topic a couple years ago). The phone itself does not calculate lat/lon. The phone captures the bare timebase GPS signal, uplinks the raw sat numbers to a server which calculates the actual coords and transmits that back to the phone.
But privacy issues are probably the biggest reason lat/lon is not more available for app usage.
- jamess 18y agoThat's nonsense. I know of no phone or device that does this, it's not like the calculations needed are exactly challenging even for your typical phone with a 200Mhz arm chip.
