A GPS (global positioning satellite) device will allow you to track or navigate, using information from orbiting satellites. GPS was formerly available only to the military but has become publicly available. You can even make your own homemade GPS device with a cell phone and a free piece of software.
Get a cell phone that can connect to the Internet. Any cell phone provider, such as AT&T, Verizon or Sprint, will sell you one with an unlimited data plan. This will allow you to have your GPS on at all times without incurring any extra fees.

Look for a GPS program. There are several you can download for free. They are fairly basic, giving you a simple feed from Google Earth and a dot to track, which is the cell phone. Nonetheless, they are functional and will get the job done. Programs to consider include Instamapper, Mologogo and BuddyWay.
Create a user name, password and enter your cell phone number and an email address into the site that you have chosen to work with. You will receive a text message, allowing you to download the GPS software.
Go to the URL provided. Download, and install the GPS software. Restart your phone.
Go to the main menu on your phone, and open "Applications." Select "GPS Software," and open it. You will see a map with a red blinking dot. As you move, the dot on the map will move, as well.
Log on to your computer, and go to the website where you registered. You will see the same map with the same dot on it. This will allow you to track your phone.
