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: -Constellation Arrangement GPS satellites fly in medium Earth orbit (MEO) at an altitude of approximately 20, 200 km (12, 550 miles). Each satellite circles the Earth twice a day. Expandable 24-Slot satellite constellation, as defined in the SPS Performance Standard.
Detailed explanation-3: -How does GPS work? GPS relies on very accurate atomic clocks carried on the satellites. Each satellite emits signals that enable receivers to determine their location and time, according to the FAA.
Detailed explanation-4: -GPS stands for Global Positioning System, and it lets us know where we are and where we are going anywhere on Earth. We still need objects in the sky to know where we are and how we get to other places, but now we use satellites instead of stars.
