GPS stands for Global Positioning System and uses 24 satellites constantly orbiting the earth to determine the position, speed and direction of an object on earth. It is used extensively in tracking moving objects, mainly vehicles and assets. GPS is can be accurate to approximately 10 meters, or less so can be used to provide geo-fencing capabilities.

A geofence is a pre-set area beyond which an asset can't travel. By using BOX technology it is possible to send alerts or even shut-down assets when they travel out side these geographical boundaries.
