GPS or a Global Positioning System is one example of a highly complex technology being deployed for use in common applications used by the public. There are 24 satellites circling the earth 24 hours at a distance of 12000 miles, and they relay coded signals to earth constantly.

Actually, your GPS receiver compares the time information when it was sent and received by the receiver to calculate the relative distances from different satellites to estimate the position of the receiver.

The latest technology has made it possible to determine the position to the accuracy of less than 15 meters. Imagine a receiver in the ocean or the uninhabited wild; you can imagine what a great advantage there is to a system that gives the position so accurately day or night and any weather conditions. We’ve come a long way from lighthouses used for navigation!

Tracking devices enabled with GPS have been used by fleet owners to monitor the position of each of their vehicles at any given time, and even allow a trucking company to know if their drivers are obeying the speed limits.  Similar applications have been introduced to consumers as well. It is now possible to have a GPS locator put on your car in the event  it is stolen, and now even to add one to your teenage daughter’s car so that you know she is where she belongs.

Additionally, there are now personal tracking devices that can be utilized by anxious parents and adult children of the elderly and infirm.
