SOLAR SYSTEM

Detailed explanation-1: -An atomic clock synchronized to GPS is required in order to compute ranges from these three signals. However, by taking a measurement from a fourth satellite, the receiver avoids the need for an atomic clock. Thus, the receiver uses four satellites to compute latitude, longitude, altitude, and time.

Detailed explanation-2: -GPS is a satellite-based navigation system that uses satellite signals in order to identify a receiver’s geographic location. Satellite navigation systems refer to a constellation of satellites that provide worldwide navigation, location, and timing services.

Detailed explanation-3: -What is the GPS Satellite System? The 24 satellites that make up the GPS space segment are orbiting the earth about 12, 000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7, 000 miles an hour.

Detailed explanation-4: -When the receiver estimates the distance to at least four GPS satellites, it can calculate its position in latitude, longitude and height.

Detailed explanation-5: -A global positioning system (GPS) device uses data from satellites to locate a specific point on the Earth in a process called trilateration.
