Question: How Accurate Are GPS Coordinates?

How accurate can GPS be?

If you can use at least four ranges, then we think you can achieve a location accuracy of about one to two meters in most buildings.

So, in the near future, any time there are RTT access points in the vicinity of a phone, the estimated position accuracy will be greater.

Can GPS tracking be wrong?

Yes but it is more accurate to state that the tracker will not accurately read your precise location due to GPS interference. Many new people choose a gps trackers because they are so reliable, OR at least they are claimed to be reliable. If a GPS is wrong, it is most likely due to GPS interference.
