Q. What is GPS?
A. The Global Positioning System (GPS) is a satellite positioning system. A
constellation of satellites broadcasts signals around the world that can be used by GPS
receivers to determine positions using triangulation. The signals are free and can be
received anywhere on Earth where there is a clear view of the sky.
Q. How accurate is the GPS receiver?
A. GPS accuracy ranges from 20 meters to 100 meters. Most of the time the GPS is
accurate within 30 meters, which is about 32 yards.
Q. What is an ideal GPS environment?
A. The GPS receiver requires an open, clear view of the sky. Buildings, covered
parking areas, tunnels, and dense foliage can hinder the GPS signals. Weather
conditions do not impact the performance of GPS. If you are parked in a covered
parking lot or near a tall building, it is recommended that you move away to have a
clear view of the sky and then use PC*MILER|Mobile. The phone should be attached
to the windshield in the holder for best performance.
