Cell Phone Gps

By: Ray Sabo

A map of the world at your fingertips seemed impossible only a few short years ago. Today it is nothing unusual. In the same way, it has become common for people to be able to use a cell phone GPS navigation systems to find directions to anyway. Just as amazing is the fact that the GPS in cell phones provides the direction for police and emergency workers to find you in an emergency situations or even to locate a missing person. More and more people are utilizing this development.

So, how does it work? GPS works by sending out signals that are picked up by GPS receivers. The Global Positioning Satellite (GPS) analyzes the signal and relays the information on to the user. Although originally designed for government use, the ability of GPS to determine the position, speed, and direction of a cell phone has brought the popularity of cell phone GPS into the lives of ordinary citizens.

Many people wonder how we tracked cell phones before GPS. This was done using a method called triangulation. This works by determining which three cell phone towers to which the phone is closest. We can then determine the approximate location of the cell phone. Now that cell phone GPS is available, though, we choose to use it instead of triangulation due to its accuracy. Cell phone GPS can pinpoint the location of a cell phone within about five meters, which is up to ten times the accuracy given to us by triangulation.

The use of cell phone GPS have helped to save lives and continue to help. Since the cell phone GPS is nearly pinpoint accurate, it can help with both emergency 911 calls as well as missing person situations. For instance, if a person is missing, and his or her cell phone is left on, the phone can be traced using the GPS. This is an amazing advantage to the investigation. Today, most cell phones have GPS capabilities so when someone calls 911, the phone sends the GPS information to the 911 operator.

In recent years, due to the compact size of cell phones, cell phone navigation systems, such as VZ Navigator, brought to us by Verizon Wireless, have become very popular. Systems like these give the user access to various maps, and, when two locations are entered into the phone, show directions from one place to the next. In today's fast paced, technological world, such a small, yet advanced tool has gained a lot of positive notoriety.

The many useful aspects of cell phone GPS are responsible for its entire popularity. Although there are other ways and tools to achieve basically the same results as those given to us by cell phone GPS, the small size, great accuracy, and easy mobility of cell phone GPS applications and features have led to not only increased accessibility for it users, but higher safety as well.
