GPS stands for Global Positioning System. The United States of Department of Defense built the GPS as a satellite radio navigation system. GPS was originally built for military use only but the United States government later on granted the petition to let it be available to the general public. This was around the 80s when the system was still in its infancy. The three important components of GPS is the satellite, earth monitoring stations and the GPS receiver. These are currently 24 satellites orbiting the earth with each satellite completing two orbits around the earth each day. These satellites transmit signals over the earth to calculate the position of the receiver. Simply put, GPS pinpoints the location of a person anywhere in the face of the earth. There are four unmanned monitoring stations located in the US and one master station. The four stations relay position data from the satellite to the master station which in turns relay date back to the satellite. This ensures that the data is checked and rechecked to make sure that the data your receive on your GPS is accurate. A GPS receiver receives the signal transmitted by the satellites. To know your locate, you have to receive a signal from at least three satellites. It will triangulate your position in terms of latitude and longitude.
