How does the GPS? Well, basically, there are three elements that make it all work: satellite, stations for monitoring the earth and receivers (eg mobile phone, cell phone). GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time.

Today, the majority of mobile phones (cell phone) are not limited to just make a conversation. Features such as mp3 player, digital camera and video camera has become the latest standards of cell phone models. It is hoped that the GPS feature will soon be added to this list, and that will offer the ability to track any cell phone user.

The ability to track a cell phone user becomes important in emergency situations, such as a car accident, through the use of the phone call emergency 911, where every minute can be a matter of life or death. In situations like this, the GPS system can pinpoint the exact location of traffic accidents, allowing emergency services to be sent quickly.

Although there are many advantages in using GPS cell phones (cell phone), there are some people who are concerned about the violation of personal privacy. From the U.S. Congress He has not authorized the actual location tracking, without evidence of wrong doing, there have been court hearings that they had not approved applications for government agencies to get the cell phone GPS tracking information from suspects or ordinary citizens.

This privacy issue has made some progress towards the mobile phone user`s rights, as there are some laws that have been passed to ensure that users of cellular phones GPS will have some kind of protection for the release of information monitoring, with the exception of 911 emergency calls from cell phone (cell phone). It is expected that these laws ensuring that the benefits of GPS in cell phones will be enjoyed by all without attacking anyone `s privacy.
