Used to calculate location, velocity and elevation, trilateration collects signals from satellites to output location information. GPS works through a technique called trilateration.
User equipment - GPS receivers and transmitters including items like watches, smartphones and telematic devices.There are monitoring stations on almost every continent in the world, including North and South America, Africa, Europe, Asia and Australia. Control activities include tracking and operating the satellites in space and monitoring transmissions. Ground control - The Control Segment is made up of Earth-based monitor stations, master control stations and ground antenna.Space (Satellites) - The satellites circling the Earth, transmitting signals to users on geographical position and time of day.GPS is made up of three different components, called segments, that work together to provide location information. The fourth satellite also moves us into the third-dimension and allows us to calculate the altitude of a device.
While we only need three satellites to produce a location on earth’s surface, a fourth satellite is often used to validate the information from the other three. The satellite system consists of a constellation of 24 satellites in six Earth-centered orbital planes, each with four satellites, orbiting at 13,000 miles (20,000 km) above Earth and traveling at a speed of 8,700 mph (14,000 km/h). The Global Positioning System (GPS) is a navigation system using satellites, a receiver and algorithms to synchronize location, velocity and time data for air, sea and land travel.

GPS helps you get where you are going, from point A to point B. You can find GPS systems in your car, your smartphone and your watch.
GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization.
