Global Satellite Positioning
GPS, “Global Positioning System.” GPS is a satellite navigation system used to determine the ground position of an object. GPS technology was first used by the United States military in the 1960s and expanded into civilian use over the next few decades. Today, GPS receivers are included in many commercial products, such as automobiles, smartphones, exercise watches, and, IoT devices.
The GPS system includes 24 satellites deployed in space about 12,000 miles (19,300 kilometers) above the earth’s surface. They orbit the earth once every 12 hours at an extremely fast pace of roughly 7,000 miles per hour (11,200 kilometers per hour). The satellites are evenly spread out so that four satellites are accessible via direct line-of-sight from anywhere on the globe.
Each GPS satellite broadcasts a message that includes the satellite’s current position, orbit, and exact time. A GPS receiver combines the broadcasts from multiple satellites to calculate its exact position using a process called triangulation. Three satellites are required in order to determine a receiver’s location, though a connection to four satellites is ideal since it provides greater accuracy.
In order for a GPS device to work correctly, it must first establish a connection to the required number of satellites. This process can take anywhere from a few seconds to a few minutes, depending on the strength of the receiver. For example, a car’s GPS unit will typically establish a GPS connection faster than the receiver in a watch or smartphone. By memorizing its previous location, a GPS device can quickly determine what satellites will be available the next time it scans for a GPS signal.
