GPS technology lets us find out the location of a vehicle, a pet, or a family member. That obviously includes the kids or teens in the family, too. What happens is that the location of the GPS receiver is obtained from the GPS set of satellites and is displayed, overlaid on a map background. If you have a receiver on your car, typically, the navigation systems will tell you not only where you are but give you directions for going from point A to point B. It will actually tell you where to take a turn. So, there’s quite a bit of value addition on these processor based GPS receivers. Most navigation systems will tell you verbally where to take a turn.
It is not hard to imagine a simpler GPS device which sends the position information to a control center. You would then be able to monitor a specific car, a fleet of taxis, or any other vehicles. You can also have such a device on the person of your child or teenager, and you could get the location information for them from time to time. A service provider receiving such GPS information from children can arrange to send you this information for you to view it on a map. You can simply have an alert sent to you periodically intimating you of the position of your kid. You may only be interested in knowing if your kid reached school or is staying within a perimeter you have set up. Alerts can be sent to you to let you know of these events.
One approach is to actually have a GPS receiver that the person carries or even just wears it in his/her shirt pocket or is a part of clothing some way. Now that cell phone devices are required to carry a GPS receiver chip, the services can be operated as an extension of the communication services of the mobile phone carrier companies. It’d also be easier to convince a child to carry the mobile phone all the time. They are likely to do it anyway.
