A few years ago, constantly having a map of the world at your fingertips seemed impossible. However, today it is a common amenity. Using cell phone GPS people with navigation systems in their phone can directions to anywhere. In addition, GPS in cell phones provides assistance for police and investigators during emergency 911 and missing person situations. This modern development continues to gain popularity. When it was first developed, it was done so for the use of the federal government.
Now, however, GPS has leaked into the everyday lives of ordinary citizens. As phones, when turned on, constantly release signals, GPS can track them even when a call is not in progress. GPS receivers pick up the signal, and tell the user the location, direction, and speed of the cell phone.
GPS track cell phones better than triangulation that was used before GPS technology. Triangulation determines which three cell phone towers to which phone is the closest. That is how they determine the approximate location of the cell phone. Although it isn't as precise, sometimes as much as tens of meters off, it did give a pretty good indication of location. The Cell Phone GPS, on the other hand, can pinpoint the location of the cell phone within about five meters.
That makes the GPS roughly ten times more accurate than 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. GPS in cell phones has seen major growth over the past few years.
Its extremely helpful and convenient features have brought GPS from the government into the everyday lives of ordinary people. This change in scenery has aided in the greatly increasing popularity of GPS. Because of this popularity, GPS will, very likely, continue to see growth in its features and usability in the near future. Ray Sabo http://www.cellphones-mp3.
