Detailed explanation-1: -The global positioning system (GPS) is a network of satellites and receiving devices used to determine the location of something on Earth. Some GPS receivers are so accurate they can establish their location within one centimeter (0.4 inches). GPS receivers provide location in latitude, longitude, and altitude.

Detailed explanation-2: -Satellites are the cornerstones of modern positioning and navigation. They are used by vehicle navigation systems, smartphones and land surveyors alike. On the basis of satellite signals, the receiver can define its position anywhere in the world with an accuracy of a few metres in less than a minute.

Detailed explanation-3: -The Global Positioning System (GPS) is a constellation of orbiting satellites that provides position, navigation, and timing data to military and civilian users globally.

Detailed explanation-4: -Constellation Arrangement GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20, 200 km (12, 550 miles).

Detailed explanation-5: -The Global Positioning System consists of 24 satellites, that circle the globe once every 12 hours, to provide worldwide position, time and velocity information. GPS makes it possible to precisely identify locations on the earth by measuring distance from the satellites.
