Quality Example
Error much greater

"Quote from the third link - the altitude error is much greater because it is a satellite based system"

from question "How accurate is the altitude measurement in mobile phones"

More

"Vertical position altitude needs one more satellite in view at least 4 so is not always reliable if gps sees only 3 satelites"

from question "Why is CLLocation's Vertical Accuracy better than it's Horizontal Accuracy?"
