on the ground it communicate with satellites that orbit the Earth.There are currently
27 GPS satellites in orbit
– 24 are in active use and 3 act as a backup in case
another satellites fails.
In order to determine your location, a GPS receiver has to
determine:
The locations of at least three satellites above you
Where you are in relation to those satellites
The receiver then uses
trilateration
to determine your
exact location. Basically, it draws a sphere around each of
three satellites it can locate. These three spheres intersect
in two points
– one is in space, and one is on the ground.
The point on the ground at which the three spheres
intersect is your location.
Warning:
A GPS receiver has to have a clear line of sight to
the satellite to operate, so dense tree cover and buildings
can keep it from getting a fix on your location. Use the GPS
based services outdoors for best results. GPS positioning
can take up to 5 minutes.
Turn on gps touching the GPS icon so that it lights up blue, like on the picture on the
right.
