How GPS Determines a Location
By applying mathematics distances between the receiver and the position of 3 or more satellites are determined. Assuming that the positions of the satellites are known in advance and the location of the receiver is calculated by determining the distance from each of the satellites to the receiver. GPS takes these references and measured distances and "triangulates" an additional position.

GPS satellites are orbiting at an altitude of 11,000 miles from earth. Satellites can be adjusted periodically by large land-based radar systems. Therefore locations of the satellites are known in advance. GPS receivers store this orbit information for all the GPS satellites is known as an almanac. Each GPS satellite broadcasts the almanac continually. Then GPS receiver automatically collects this information and stores this information for future use.

The Department of Defense continually checks the orbit of the satellites looking for deviations from predicted values. Any deviations, which are caused by natural atmospheric phenomenon such as gravity are known as ephemeris errors. When ephemeris errors are determined then the errors are sent back to the satellite, which in turn broadcasts the errors as part of message and supply this information to the GPS receivers. By using ephemeris error data in conjunction with the information from the almanac, the position of a GPS satellite can be determined for a given time.

By measuring the amount of time a radio signal takes to travel from the satellite to the receiver, GPS determines distance between a GPS satellite and a GPS receiver. Radio signals travel with speed of light. If the amount of time the signal takes to travel from the satellite to the receiver is known then the distance between the satellite and the receiver can be determined by using formula distance = speed x time. The signal's travel time can be determined, if the exact time when the signal was transmitted and received are known.

For synchronization purpose, the satellites and the receivers use very accurate clocks so that they generate the exactly same code at exactly the same time. The code generated by the receiver can be compared with the code received from the satellite. The time difference between when the satellite generated the code and when the receiver generated the code can be determined by comparing these codes. This difference between times is the travel time of the code. This travel time is multiplied in seconds to 186,000 miles per second gives the distance from the receiver position to the satellite in miles.

News & Evens
vehicle tracking system is an electronic device installed in a vehicle to enable the owner or a third party to track the vehicle's location. Most modern vehicle tracking systems use Global Positioning System (GPS) modules for accurate location of the vehicle. Many systems also combine a communications component such as cellular or satellite transmitters to communicate the vehicle’s location to a remote user. Vehicle information can be viewed on electronic maps via the Internet or specialized software.
