Introduction: GPS Basics

•! Four satellite signals are needed to locate the receiver in 3D space.

•! The fourth satellite is also used for time accuracy.

•! Position can be calculated within to a millimeter.

Demonstration !Pinpoint Location With GPSPinpoint Location With GPSPinpoint Location With GPS

How to demonstrate this:

/watch?feature=player_embedded&v=s_C

eiMjO5Pc#!

One way to find your location – !4 intersecting spheres

One satellite, the GPS could be anywhere on the edge of the sphere.

Two satellites, GPS could be on the circle

where spheres

intersect.3 satellites: spheres intersect in 2 places.

4 satellites, spheres

intersect in one place.
