GPS Receiver

A GPS receiver is one part of a GPS system. The GPS receiver is an electronic device, which can be mounted to a vehicle or held by hand, that receives the global positioning system signal so that it can be processed. The GPS is configured using twenty four satellites which orbit the earth in a specific pattern, so that there should be four satellites at a minimum which the receiver can receive signals from, at any time of the day or night anywhere on earth. The GPS receiver will locate as many of the GPS satellites as is possible, but there needs to be at least three satellite locations used or the receiver can not get enough information for processing and an error may occur. The receiver uses these satellites as points of reference, figuring the distance to each satellite and then using the information from multiple satellites to lock the exact location of the receiver. This method is called trilateration, and it uses a simple mathematical principle by the same name. By using three or more satellite signals, the receiver can accurately find your location. The more satellites a receiver uses during the process, the more accurate the data will be. A GPS receiver is necessary to use the Global Positioning System. Without the receiver, no signal will be received, and locating the specified target is not possible. The receiver is also what makes it possible for your car to be traced by police if it is ever stolen, leading to a quick recovery of the vehicle, and less damage to be repaired in some cases. Cell phones are also being marketed to parents that have a GPS receiver inside. These cell phones are given to kids, and parents can track the movements and locations of their children by using the GPS receiver that is included.
