SSC MTS EXAM

Detailed explanation-1: -GPS receivers provide location in latitude, longitude, and altitude. They also provide the accurate time. GPS includes 24 satellites that circle Earth in precise orbits. Each satellite makes a full orbit of Earth every 12 hours.

Detailed explanation-2: -The control segment uses measurements collected by the monitor stations to predict the behavior of each satellite’s orbit and clock. The prediction data is up-linked, or transmitted, to the satellites for transmission back to the users.

Detailed explanation-3: -Over 30 GPS navigation satellites are whizzing around the world, orbiting at an altitude of 20, 200 Kilometers, to help us find our way. GPS is a three-part system: satellites, ground stations, and receivers. Satellites act like the stars in constellations-we know where they are supposed to be at any given time.
