As many of you already know, the Global Positioning Satellite System (GPS) has a number of major benefits. It can be of huge assistance to those navigating in unfamiliar territory. But some people consider it to be an invasion of privacy. GPS security and privacy, has been widely discussed and many adults believe that the pros out weigh the cons.

These handy little pieces of electronics can tell one much more than simply the current place where they are standing. With a little bit of training, the data can be used as a speedometer, odometer, and homing beacon. The functions are virtually limitless to the creative mind.

At times, individuals perceive this as an invasion of privacy. For instance, most customers fail to read the fine print on car rental contracts that states additional charges will be accrued if the driver exceeds a speed of 79 miles per hour. The GPS tracking mechanisms employed by rental companies could record the incidence and frequency of times when drivers do exceed this limit, and charge the credit card on file an added wear and tear fee based on this information.

Although some people worry about the invasion of privacy issues with GPS devices, most parents find that knowing that their child can be found if necessary trumps the privacy issues. Parents have been known to use cell phones to track a child's actions and movements. If the parents find that the child has disobeyed, they might lose privileges, such as driving or going out.

GPS cell phones no longer require people to purchase expensive hardware to track a loved one. Cell phone companies now offer this option. However most cell phones do not offer the user direct access to the GPS data. Accurate location determination requires the assistance of the wireless network, and the GPS data is transmitted only if a 911 emergency call is made.

Greater peace of mind and comfort are important when it comes to cellular telephones. Most folks don't realize they can actually be traced with their cells. The cops can use these to find crime doers and their victims, and even stolen cars. Each year there are more innovative versions of these devices with new bells and whistles. These gadgets can make us, and our families and friends feel safer and more connected. One caveat, however is that the data these devices contain might be subject to abuse.
