Lat/lon are in thousandths of a second of arc. If I did my math right, that means the worst-case precision is a hair over 3cm. Altitude is in centimeters, so on a comparable scale.

Looks to me like it is accurate enough to locate even the smallest network-connected devices! Provided someone doesn't invent wifi-connected rice grains, of course.

This should be a standard feature of server cages. The base rack itself could have a GPS receiver and provide the relative location of each rack.

That way when you nudge the rack over a few feet to make room for the foosball table it automatically updates its own physical location.
