Global Positioning System (GPS)

Peripheral Use of the System

a. Introduction of the Subject

Nowadays, the word "maps" are becoming less popular and has evolved into the word "GPS". Simply, the Global Positioning System is a system of satellites and receiving devices used to compute positions on Earth. The information can be used in a three-way communication for use as positioning system.

After much evolution of the GPS technology, it is very useful in tracking down an individual- not only humans, but also animals. A tiny modem, attached to their collar, sends out a text message to a mobile phone, PDA, or other two-way wireless device, whenever a pet leaves any predetermined boundaries. Not only is the owner notified, but the receiver gives directions, and even maps, with certain supported mobile phones, for finding the wandering pet.

Many mobile phones, PCs or PDAs already have real-time tracking software readily installed in them, making it accessible and easy to operate. PawTRAX(tm) is an example of an online program that allows users to track their pets. Users can enable geo-fences, and follow the pet's movements in real time.
