So, you may asking yourself what exactly what is a GPS devices and how do they work?
The Global Positioning System, more typically called GPS (originally called Navstar) is a satellite navigation system used to determine the exact location almost anywhere on Earth. The first GPS satellite was launched in 1978. A GPS receives signal transmissions from multiple satellites and then calculates its position through triangulation of the data. The GPS consists typically of a "constellation" of satellites. Each satellite circles the earth approximately twice each day. When comparing signals from two satellites, the receiver (the actual GPS device) can compute the difference between the distances to these two satellites. A GPS can calculate the exact location through a system of complex (nonlinear) equations.
Once the GPS receiver's position and distance the satellite is known, the time signal sent out by one of the satellites makes it possible to calculate receiver position. If the elevation information is not necessary, only three satellites need to be contacted. Calculations are complicated by the fact that speed of radio waves is not constant in the atmosphere are impacted by atmospheric conditions and the angle of entry, among other factors. GPS units contain a mathematical model to account those influences and satellites also emit some related information that helps the receiver to the correct estimate of speed and rate of travel.
