WHAT IS GPS?
The Global Positioning System (GPS) is a system of 24 satellites that circle the earth
twice a day in a very precise orbit and transmit information to earth. The Forerunner must
continuously “see” at least three of these satellites to calculate your location and track your
movement. At times, additional satellites may be needed to determine a location. If some of
the satellites in view get blocked or “shaded,” the receiver can simply use an alternate satellite
to maintain the location fix.
Because the Forerunner relies on satellite signals to provide you with navigation guidance,
the receiver needs to have an unobstructed, clear view of the sky for best performance. In a
nutshell, the GPS receiver’s view of the sky generally determines how fast you get a location
fix, or if you get a fix at all. GPS signals are relatively weak and do not travel through rocks,
buildings, people or metal, so remember to keep a clear view of the sky at all times for best
performance.
Your Forerunner needs to be given the opportunity to find or Autolocate itself (“initializa-
tion”). Once you initialize the unit to a location, it typically computes a fix within a couple
minutes.
Longer initialization (Autolocate) is only necessary:
• The first time you use your Forerunner (new from the factory).
• After the receiver has been moved over 500 miles (with the power off from the last time
you used it.
