How Does GPS Navigation Work?


Global Positioning System (GPS) navigation gets its transmission from GPS satellites. These systems act only as receivers but they cannot transmit signals. They require an unobstructed view of the sky to receive these signals, so they are more functional outdoors. While on the road, a motorist may be in an area where tall trees stand close to each other, creating a canopy that blocks the view of the sky, or travel to a city crowded with tall buildings. Under such conditions, the GPS navigation has trouble receiving transmissions. Each GPS satellite transmits data that contains the time, precise orbital information, the general system health and rough orbits of every GPS satellites. The recipient in turn, interprets this data.
