Since last night's announcement, there has been a lot of speculation surrounding the Galaxy Nexus. One of the most mysterious features of Samsung's latest Nexus device is its onboard barometer. Many have been questioning why Samsung would include a barometer in the Nexus' sleek chassis, citing possibilities from more accurate weather prediction to simple altitude detection (which is partially true).
In a Google+ post today, Android Engineer Dan Morrill gave us the scoop on what the barometer is actually for, and it's more interesting than you might think.
Morrill explains that the barometer is actually intended to speed up GPS location, because "locking onto a GPS involves numerically solving a 4-dimensional set of linear equations - 3 dimensions in space, and time."
That sounds a bit complicated, doesn't it?
