New GPS (Global Positioning System) chips will be used in future cell phones that will be accurate within 30 centimeters (11.8 inches), rather than five meters (16 feet) which is typical of today’s cell phones. At least, that’s the claim chip maker Broadcom is making. While this may not seem at first to be significant for genealogists, it should greatly improve the accuracy of locations recorded with a cell phone and its camera.
Millions of tombstones are already recorded today with accuracy of plus or minus 16 feet or sometimes even worse accuracy than that. Sixteen feet sounds like reasonable accuracy in many cemeteries, but it still is not good enough for quick location of tombstones in many family plots and certainly not close enough for pinpoint accuracy in a columbarium, a room or building with niches where funeral urns are stored.
The recent announcement from chip manufacturer Broadcom says that some of its next-generation smartphone chips will use new global positioning satellite signals to boost accuracy. In a detailed report on the announcement, IEEE Spectrum says that the new chips, which are expected to appear in some phones as soon as next year, will also use half the power of today’s chips and will even work in cities where tower blocks often interfere with existing systems.
I doubt if users of BillionGraves.com and FindAGrave.com will go back and re-visit all of the millions of locations already listed in those sites. However, as the new chips are used in more and more cell phones, the accuracy of future additions to those databases should be greatly improved.
